Vertex Data (Vertex Buffers) |
|

of model data. The sample creates a textured cube as an
example. Check out the OpenGL source
code page for a Vertex Array sample which is OpenGL's equivalent
of Direct3D's Vertex Buffers.

Indexed Geometry |
|
This sample demonstrates how to optimize performance by
using indexed geometry. As a demonstration, the sample
reduces the vertex count of a simple cube from 24 to 8
by redefining the cube’s geometry using an indices array.

code page for the OpenGL equivalent of this sample.

Transforms |
|
Demonstrates how to use concatenated translation, rotation,
and scaling matrices to create a simulated solar system.
And as a small bonus, the sample also demonstrates how
to optimize Direct3D applications using a matrix stack
to prevent continuous changes to the view matrix, which
can kill your apps draw time.
On an unrelated side-note, the sample also shows how to
clone a mesh so you can add additional properties to its
FVF code or vertex layout. The sample uses D3DXCreateSphere
to create test spheres, which originally have no color.
I then clone the mesh and add colors to them for demo purposes.

code page for the OpenGL equivalent of this sample.
