Program 20 – Projected textures
03.08.2002
Texture projected on objects is interesting effect. This makes it possible do interesting lighting of scene, example uses light through stained glass.
Program 19 – Sphere mapping
26.07.2002
Sphere mapping is technique of environment mapping. This uses a sphere map. A sphere map is a single texture of a perfectly reflecting sphere in the environment where the viewer is infinitely far from the sphere.
Program 17 – Motion blur
09.07.2002
Unlike cine-camera where fast moving objest are blurred, each image rendered in OpenGL is sharp. This causes discontinuous motion also above FPS.
Program 16 – Shadows by render to texture
06.07.2002
Shadows are make with light maps. Light maps are created with render to texture. Light map was creat for each wall, so camera is moved to light position and draw with dark color all objects which cast shadows. This technique is possible used only shadows which cast to planar surfaces.
Program 15 – Render to texture
03.07.2002
Rendering to texture is interesting technique. That makes it possible to creates various effects: motion blur, radial blur, …
This works simple: uses glCopyTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 0, 0, size, size, 0); to copy data from screen to texture.
Program 14 – dxf loader
26.06.2002
These files export AutoCad or CADKEY. I load only quadrilateral surfaces – data from 3DFACE sections. Name of level uses for texture name.
Program 13 – 3ds loader
26.06.2002
3ds files is possible export from 3ds max. In files are store texture coordinations and texture names.
