I could see there being numerous examples based around textures. The current "texture" examples are meant to be simple examples of how to send texture data to the GPU and map it onto a quad. We should probably have additional non-shader examples like "textureFromImage" and "textureMapFromImage". Since modelShader.cpp is doing more than loading/displaying a model perhaps it should be called "textureMapModel" or something...

None of the three "texture" examples do what I think of as the most basic way of dealing with a texture (i.e., reading a texture image from a file and UV-mapping it onto a mesh). The one that does doesn't have "texture" in its name. Am I just being dense or is this confusing?

examples/graphics/modelShader.cpp loads an image, creates a texture, and applies it to a duck.

We should make an FBO example to demonstrate Texture:quad(), if we haven't already.

All of the examples I can see regarding textures involve procedurally generating the texture on the CPU and then applying them in a shader:

examples/graphics/shaderTexture.cpp examples/graphics/texture.cpp examples/graphics/texture3d.cpp

I'd like to see another example in which a texture is read from a file on disk (via the proper search paths mechanism?) into the appropriate CPU data structure (al::Image?) then submitted as a texture to the GPU, then "texture mapped" in the usual way (http://en.wikipedia.org/wiki/Texture_mapping) onto a simple 3D model.

It would also be nice to have an example showing the usage of Texture:quad().

Thanks! -Matt

i added textureImage.cpp in response to this request. closing this issue.
