This makes graphics pipeline very flexible but + in the same time it becomes more difficult because user has to implement graphics + pipeline to get even the simplest example running. It also makes graphics pipeline + more efficient because user can decide what kind of pipeline is needed for the + application. + + First we have to implement vertex shader. It gets vertex data and + model-view-projection matrix (MVP) as parameters. It transforms vertex position + using MVP matrix to screen space and passes texture coordinate to + fragment shader. Texture coordinate will be automatically interpolated on polygon + faces. + + \snippet examples/opengl/cube/vshader.glsl 0 + + After that we need to implement second part of the graphics pipeline - fragment + shader.

OpenGL has a mechanism to create buffer objects to this memory area and + transfer vertex data to these buffers. In OpenGL terminology these are referred + as Vertex Buffer Objects (VBO). + + \image cube_faces.png Cube faces and vertices + + This is how cube faces break down to triangles. Vertices are ordered this way + to get vertex ordering correct using triangle strips. OpenGL determines triangle + front and back face based on vertex ordering. By default OpenGL uses + counter-clockwise order for front faces. This information is used by back face + culling which improves rendering performance by not rendering back faces of the + triangles. This way graphics pipeline can omit rendering sides of the triangle that + aren't facing towards screen. + + Creating vertex buffer objects and transferring data to them is quite simple using + OpenGL provided functions. + + \snippet examples/opengl/cube/geometryengine.cpp 0 + + \snippet examples/opengl/cube/geometryengine.cpp 1 + + Drawing primitives from VBOs and telling programmable graphics pipeline how to + locate vertex data requires few steps.
