We have listened to our customers and decided to release the 30-Day Trial Edition of Tgi3D SU Amorph so that our customers can test the product without the vertex count limitation imposed on the Free Training Edition. You can download the 30-Day Trial Edition from the Downloads page on Tgi3D website.
Tgi3D SU Amorph Free Training Edition lives on...
Rest assured that this announcement does not mean that the “ever popular” Free Training Edition of Tgi3D SU Amorph is abondoned. You can continue to use the Free Training Edition, but if you are thinking about the next step to purchase the plugin and want to experience the full capabilities of Tgi3D SU Amorph before the decision, you now have a chance to do so.
We are happy to announce the release of the new versions of Tgi3D plugins (v1.21). As always, you can download the new versions from the Downloads page on Tgi3D website.
We have some of the most wanted and anticipated improvements in this release.
1. Tgi3D now loads much faster at start up!
2. The texture map is preserved during Tgi3D's own edit operations, i.e. the texture map dynamically adjusts as the surface is edited.
3. You can “safeguard” and then “restore” texture maps for other edit operations that break the texture.
4. You can optionally compress the Tgi3D context menu items to be accessed through “Tgi3D commands” submenu.
To do this:
-- Click on the Tgi3D Settings button on Tgi3D toolbar.
-- Turn off the "Direct context menu access to Tgi3D commands" option under "Global Settings" in “Tgi3D Settings” dialog.
Upgrades of Tgi3D SU plugins have just been released! You can download the new versions from the Downloads page on Tgi3D website.
The new releases include a new downsampling feature to reduce the polygon count of a model while preserving the model fidelity in a controllable fashion. There are also some exciting updates to the existing features, such as a “clean Bezier surface” option for mesh creation and preservation of texture.
Below are the details of the updates in the new releases:
Introduced "Downsample" command to decrease the resolution of a mesh
Create mesh can nowcreate Bezier (i.e. parametric) surfaces, if the boundary is
A quad of bezier curves and the number of samples on opposite curves match
A triangle of bezier curves and the number of samples on the longest two sides match
Introduced "Collapse" command to collapse the selected region to a point
Mesh editing (upsample and downsample) results are placed in a Sketchup group optionally to allow faster processing.
Cross Section Tool now supports measured motions.
(Mac) Plugin now works on Mac OS X v10.5.x.
(Upsampling & Downsampling) Preserve the texture mapping during upsample and the new downsample
(Texturing) Preserve SketchUp assigned material transparency in texture creation
(Texturing) Preserve the horizontal and perpendicular structures (e.g in buildings) in unwrap mode of texture mapping
(Texturing) Preserve material transparency and color in the texture mapping.
(Texturing) Do not display uv map in the texture if the seperate uv map output is selected.
(Move tool) Improved Bezier curve editing.
In addition to the updates included in Tgi3D SU Amorph, Tgi3D SU PhotoScan includes the following fix.
(Calibration Tool) Added user warning if a camera can not be found in the built-in or local database
We are very happy to announce that we have just released the new versions of our plugins which are now also available for Mac users! You can download Free Training version of Tgi3D SU Amorph and 30-Day Trial version of Tgi3D SU PhotoScan from the Downloads page on our website.
There is also good news for Microsoft Windows users! The new releases come with a new smart texturing feature and other enhancements to the existing features which are detailed below. We also encourage you to update your versions of Tgi3D plugins and try the new versions.
The updates include:
Mac OS X support!
New smart texture creation and mapping feature which enables you to easily create, seamlessly merge and paint image textures on smooth curved surfaces, while keeping existing image textures. The produced texture images can be accessed from Sketchup's Materials window and edited with your favourite image editor. Below is the video of the new feature.
Enhancement to existing features:
Tgi3D Move Tool now supports vertex snapping (via pressing Shift key during move)
Tgi3D Select Tool now has a face tagging option where the user selects a group of faces and tags them to be able to reselect them later with a single click.
Tgi3D Cross Section Tool now works with user selected closed loops.
Small fixes
Tgi3D Costruction Point Tool correctly places construction points inside the component under component edit.
Tgi3D Cross Section Tool loop detection is improved.
In addition to the updates included in Tgi3D SU Amorph, Tgi3D SU PhotoScan has the following additional updates:
Tgi3D Calibration and Metrology Tool's SketchUp Export now produces a SKP file. There is no need to “import Tgi3D calibration” in Sketchup anymore. The user simply loads the SKP file created by Tgi3D Calibration and Metrology Tool.
Tgi3D Calibration and Metrology Tool's 3D Viewer refresh functionality after a new measurement entry and recalibration has been improved.
Here are a few tips that may be helpful to make photoscanning complex amorph shapes easier. There is also a video showing surface fitting to photographs in action, if you haven't seen it already in Tgi3D's YouTube channel.
(1) Make sure the calibration is good. In Tgi3D Calibration Tool you can check the accuracy of the calibration by running calibration with “create calibration uncertainty (or accuracy) information” option. You can then increase the accuracy by going over the calibration points with the help of the "point errors" tab. You can add new points in different photographs to match existing calibration points or adjust the locations of existing points, and re-run the calibration process. In a human scale object the uncertainties of distances between calibration points should be at the order of millimeters for a good reconstruction.
(2) When applying surface fitting to photographs in SketchUP using Tgi3D SU PhotoScan plugin, the initial curves do not have to be exactly correct, they have to be close enough such that color based matching can arrive at the minimum from the given initial condition (a few pixels in the second picture). For that purpose actually, it is enough that one side of the surface is close to the real 3D, the rest of the surface will find its 3D location from that. The idea is to draw/match an easy (and possibly small) part of the object first, and then grow from there. You select the portion of the surface to be optimized, you do not want to spend optimization time on already optimized surface, but you want your surface to touch or include part of an already optimized surface.
(3) Also you can remove and put view locks and any part of the surface as needed. Do not hesitate to erase, repair, lock, unlock parts of surface as you see fit.
(4) If you have enough photographs, you can draw accurate curves using the silhouette of the object. This is sometimes useful. Imagine the silhouette of an arm from the side, you can draw the curve from front and if you have a side view you can position those curves from the side view. In fact if you have enough such silhouettes you can draw the object in 3D by using those silhouettes and simply creating and smoothing the corresponding surfaces without surface fitting to photographs, especially if you do not require a "numerically accurate" model.
(5) To draw curves on an object that does not have edges you may also make use of point-like features on the texture.
(6) One other thing that may be useful is to try to make the initial match with as few faces as possible. Do not increase resolution until you have a good match at lower resolution. Keep in mind though, if your resolution is too low you can never have a good match.
(7) Remember this is also a drawing tool, you can manually help the PhotoScan tool at any point, on any part of the surface with manual adjustments.
(8) For complex shapes some parts of the surface will remain hidden, or just have no texture on them, for those parts you can use smoothing operation. The smoothing operation guesstimates the surface shape from boundary conditions and softness/sharpness of the shapes.
(9) The photographs that you use should not have fake excess resolution. That is, do not increase resolution simply by changing image size in an editor. In fact, for most cameras you can decrease the resolution, decreasing the run time for PhotoScan.
(10) If you are making a really high detail model, you may want to create parts of the model in different SketchUp files, like head in one file, torso in another, legs in other etc, and then join them. SketchUp handles small polygon count files much better, try to remain under 5000-10000 faces per file, for example.
We are launching this blog to provide 3D modelers with news about Tgi3D plugins for Google SketchUp. Visit often to find out what's cooking and to learn tips about using the plugins, to view models, how-to guides, and more...
Let me start with a quick introduction to Tgi3D and its products:
Tgi3D is a registered trademark of Ocali, Inc. With the launch of our website in mid-October, 2010 we have started marketing the two sets of plugins (Tgi3D SU Amorph and Tgi3D SU PhotoScan) for Google SketchUp under this trademark. We refer to our products as “sets” of plugins, beacuse each has a number of greate features that can be viewed as seperate plugins bundled in one.
Tgi3D SU Amorph allows you to create highly sophisticated 3D models by providing tools to create and edit free form curves and amorph surfaces. You can generate and manipulate curves and surfaces, increase resolution, edit extrusions, and do more with great ease. Tgi3D SU Amorph has a freeTraining version that has the same functionality as the commercial version except that it has a limit on the number of vertices two work with in some of its features related to surface meshes.
Tgi3D SU PhotoScan presents 3D scanning capability from photographs like never seen before in SketchUp. It is now possible to create highly accurate 3D models of complex real life objects in SketchUp. The Tgi3D SU PhotoScan package includes a seperate executable called the Tgi3D SU PhotoScan Calibration and Metrology Tool, which provides state-of-the-art camera calibration and metrology capabilities that can also report measurement uncertainties accurately. When the user is satisfied with measurement accuracy, the resulting calibration is exported to Google SketchUp, where the user then draws the approximate surface on photographs and Tgi3D SU Photoscan automatically corrects the selected portions of the surface by matching the textures in photographs corresponding to the selected surface. You can try the fully functional Tgi3D SU PhotoScan with the 30-Day Trial Edition.
