VS*L has been updated to allow cube maps to be loaded as textures. Tangents and bitangents are also provided for every loaded model. The models default texture, the texture definitions of the loaded model, can now be replaced by any pre loaded texture.

VSMathLib, a part of the Very Simple Libraries framework, has suffered a minor update. The modelview matrix has been split into two matrices: model and view. The modelview matrix is still available, but now it is a computed matrix. The programmer should use the two individual matrices, model and view, and the lib will compute the modelview, actually called VIEW_MODEL, as required.

The PROJMODELVIEW has been renamed to PROJ_VIEW_MODEL since this is the actual order of the matrix multiplication.

Besides that the lib works as usual. Comments are most welcome as usual.

A sample using all the libs in the Very Simple framework is now available from the VS*L downloads page. The sample source C code, shaders, a 3D model, and textures, are provided, as well as a Visual Studio 2010 solution.

Two more libs are available in the VS*L framework. With these new additions it is possible to use Assimp to load 3D models, and render them with core OpenGL. The libs store the meshes in VAOs, and use VSShaderLib and VSMathLib to simplify the rendering with shaders with almost any uniform variable configuration.

Shaders are the core of the rendering process. OpenGL core profile requires us to provide our own shaders, no more fixed function.

Using shaders means more flexibility, but it also implies more work. This is where this lib steps in.

VSShaderLib was designed to make our life easier. It allows to create programs, load shaders from files, associate vertex attribute names with locations, and work with uniforms, including uniforms in named blocks. It also provides access to the info logs.
