示例1: init
void TerrainTessellator::init(const GraphicsDevice& device, unsigned size, unsigned numPatches, unsigned stripeSize)
{
this->size = size;
this->stripeSize = stripeSize;
this->numPatches = numPatches;
numVertices = (size + 3) * (size + 3);
unsigned lod = (unsigned)MathHelper::log2(size) + 1;
patchIndexBuffers = IndexBufferCollection(lod);
skirtIndexBuffers = IndexBufferCollection(lod);
for (unsigned i = 0; i < lod; ++i)
{
patchIndexBuffers[i] = createPatchIndexBuffer(device, i);
skirtIndexBuffers[i] = createSkirtIndexBuffer(device, i);
}
VertexCollection vertices(numVertices);
for (int row = -1; row <= (int)size + 1; ++row)
for (int col = -1; col <= (int)size + 1; ++col)
{
int r = MathHelper::clamp(row, 0, (int)size);
int c = MathHelper::clamp(col, 0, (int)size);
float y = (r == row && c == col) ? 0.0f : -1.0f;
vertices[getIndex(row, col)].position = Vector3((float)c, y, (float)r);
}
vertexBuffer = device.createVertexBuffer(sizeof(TerrainVertex) * numVertices, TerrainVertex::fvf, D3DUSAGE_WRITEONLY);
vertexBuffer.setData(vertices);
instanceVertexDeclaration = device.createVertexDeclaration(TerrainGeometry::vertexElements);
