My final graduation project is "Texture Mapping in VRML". Project is divided into two parts.
First part is mainly theoretical and concerned with VRML specification and the way textures are
supposed to look like in VRML worlds, as well as how to get that look on most real-time
3D engines. Second part is dedicated to texture mapping process with emphasis on algorithms,
filtering and speed comparisons.
I'm done with the first part and am now working on the second part of my final paper.
I plan to report on my progress on this page and fill it with my observations and VRML related software I make.
For now, you can test how VRML browser you are using is dealing with problem of mapping textures
on Cone and Sphere. If 3D engine your VRML viewer is using is triangle oriented, you'll probably
get really bad results.
These problems and possible solutions are discussed in first part of my final paper.
Both test worlds contain two objects of the same type. Right object is the default VRML object, while the left one is generated using software I made. Objects are mapped with test texture (GridTestSmallGray.jpg (22K) - small and grayscale to reduce download time), designed to enhance possible problems and distortions.
Click on the links below and use examiner view or move around objects to see what they look like.
| Cone Test (VRML World) | Sphere Test (VRML World) |
| Objects are cones with bottom radius 3 and height of 6 meters. Look out for possible distortion of texture on the body of the right cone. | Objects are spheres with radius of 3 meters. Distortions could appear in the polar regions of the right sphere. |
Don't forget to check out the links section and see if maybe I found some interesting sites you don't know about.
