How
to use the Tokamak SDK to Create a Stack of Blocks |
|
This sample demonstrates how to use the Tokamak
Physics SDK to create a stack of blocks which can
be knocked over. For demonstration purposes, you can
use the F1 key to lift up and drop the bottom block,
which will obviously disturb the stack. You can also
use the F2 key to tilt the blue platform and dump the
blocks over the side. Check out the OpenGL source
code page for the OpenGL equivalent of this sample.

Using the Attributes
Table of D3DXMesh to Render Sub-sets |
|
This sample demonstrates how to
manually load the vertex buffer of
a single ID3DXMesh object with three
separate colored quads. We then use an
attribute table to ID these three quads
so we can render them separately as
subsets of the mesh using DrawSubset.
The sample also demonstrates how to use
the ID3DXMesh methods GenerateAdjacency
and OptimizeInplace to optimize our test
mesh.
