示例1: setupVertices
//-----------------------------------------------------------------------
void InstanceBatchHW::setupVertices( const SubMesh* baseSubMesh )
{
mRenderOperation.vertexData = baseSubMesh->vertexData->clone();
mRemoveOwnVertexData = true; //Raise flag to remove our own vertex data in the end (not always needed)
VertexData *thisVertexData = mRenderOperation.vertexData;
//No skeletal animation support in this technique, sorry
removeBlendData();
//Modify the declaration so it contains an extra source, where we can put the per instance data
size_t offset = 0;
unsigned short nextTexCoord = thisVertexData->vertexDeclaration->getNextFreeTextureCoordinate();
const unsigned short newSource = thisVertexData->vertexDeclaration->getMaxSource() + 1;
for( unsigned char i=0; i<3 + mCreator->getNumCustomParams(); ++i )
{
thisVertexData->vertexDeclaration->addElement( newSource, offset, VET_FLOAT4,
VES_TEXTURE_COORDINATES, nextTexCoord++ );
offset = thisVertexData->vertexDeclaration->getVertexSize( newSource );
}
//Create the vertex buffer containing per instance data
HardwareVertexBufferSharedPtr vertexBuffer =
HardwareBufferManager::getSingleton().createVertexBuffer(
thisVertexData->vertexDeclaration->getVertexSize(newSource),
mInstancesPerBatch,
HardwareBuffer::HBU_STATIC_WRITE_ONLY );
thisVertexData->vertexBufferBinding->setBinding( newSource, vertexBuffer );
vertexBuffer->setIsInstanceData( true );
vertexBuffer->setInstanceDataStepRate( 1 );
}示例2: buildFrom
//-----------------------------------------------------------------------
void LightInstanceBatchHW::buildFrom( const SubMesh *baseSubMesh, const RenderOperation &renderOperation )
{
InstanceBatch::buildFrom( baseSubMesh, renderOperation );
//We need to clone the VertexData (but just reference all buffers, except the last one)
//because last buffer contains data specific to this batch, we need a different binding
mRenderOperation.vertexData = mRenderOperation.vertexData->clone( false );
VertexData *thisVertexData = mRenderOperation.vertexData;
const unsigned short lastSource = thisVertexData->vertexDeclaration->getMaxSource();
HardwareVertexBufferSharedPtr vertexBuffer =
HardwareBufferManager::getSingleton().createVertexBuffer(
thisVertexData->vertexDeclaration->getVertexSize(lastSource),
mInstancesPerBatch,
HardwareBuffer::HBU_STATIC_WRITE_ONLY );
thisVertexData->vertexBufferBinding->setBinding( lastSource, vertexBuffer );
vertexBuffer->setIsInstanceData( true );
vertexBuffer->setInstanceDataStepRate( 1 );
