Textures in OpenGL

Here are some slides about OpenGL's support for texture mapping

Here are 3 test programs:

• TexSimpleFloat.java This defines a checkerboard texture an maps it onto a square.
• MultipleTextures.java This makes three polygons with different textures.
• AutoGenTexture.java This shows automatic texture generation
• FileTexture.java This builds a texture from the image file spots.ppm and maps it onto a spinning rectangle.
• QuadricTexture.java This shows two spinning cones. The upper one uses a quadric texture; the lower one an automatic texture.
• SplineTexture.java The puts a checkerboard texture on a bottle made from spline patches.
• SplineFileTextureSpots.java This puts a texture from the file spots.ppm onto the spline bottle.
• SplineFileTexture.java This maps the image from file Martini.ppm onto one patch of the bottle, like a label.

If you use the file textures, remember that by default Eclipse expects a file to be in the project folder, not in the src folder with your code.
