| 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. Check out the OpenGLsource code page for the OpenGL equivalent of this sample. Relevant Keywords: CreateVertexBuffer, CreateVertexBuffer, Lock, Unlock, DrawIndexedPrimitive, DrawPrimitive, D3DPT_TRIANGLESTRIP, SetStreamSource, SetIndices, SetFVF, D3DUSAGE_WRITEONLY, D3DFMT_INDEX16, , and D3DPOOL_DEFAULT. Relevant C# Keywords: VertexBuffer, IndexBuffer, Color, ToArgb, Usage.Dynamic, Usage.WriteOnly, Pool.Default, Lock, Unlock, VertexFormats.Position, VertexFormats.Diffuse, DeclarationType.Float3, DeclarationType.Float2, DeclarationType.Color, SetStreamSource, PrimitiveType.TriangleStrip, VertexFormat, Indices, DrawPrimitives, and DrawIndexedPrimitives. ![]()

| 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. Check out the OpenGLsource code page for the OpenGL equivalent of this sample. Relevant C++ Keywords: SetTransform, D3DXMatrixTranslation, D3DXMatrixRotationY, D3DXMatrixScaling, D3DXCreateSphere, CloneMeshFVF, GetVertexBuffer, GetNumVertices, D3DXCreateMatrixStack, LoadIdentity, LoadMatrix, Push, Pop, MultMatrixLocal, LPD3DXMATRIXSTACK, and LPD3DXMESH. Relevant C# Keywords: Mesh, Mesh.Sphere, Clone, Options.Value, VertexBuffer.Lock, VertexBuffer.Unlock, LockFlags.None, NumberVertices, DrawSubset, Dispose, Matrix, MatrixStack, Matrix.LookAtLH, Transform.View, Transform.World, Vector3, Matrix.Identity, RotateY, Translate, LoadMatrix, Push, Pop, and MultiplyMatrixLocal. ![]()
