示例1: setupVertexDeclaration
//-----------------------------------------------------------------------
void BillboardChain::setupVertexDeclaration(void)
{
if (mVertexDeclDirty)
{
VertexDeclaration* decl = mVertexData->vertexDeclaration;
decl->removeAllElements();
size_t offset = 0;
// Add a description for the buffer of the positions of the vertices
decl->addElement(0, offset, VET_FLOAT3, VES_POSITION);
offset += VertexElement::getTypeSize(VET_FLOAT3);
if (mUseVertexColour)
{
decl->addElement(0, offset, VET_COLOUR, VES_DIFFUSE);
offset += VertexElement::getTypeSize(VET_COLOUR);
}
if (mUseTexCoords)
{
decl->addElement(0, offset, VET_FLOAT2, VES_TEXTURE_COORDINATES);
}
if (!mUseTexCoords && !mUseVertexColour)
{
LogManager::getSingleton().logMessage(
"Error - BillboardChain '" + mName + "' is using neither "
"texture coordinates or vertex colours; it will not be "
"visible on some rendering APIs so you should change this "
"so you use one or the other.");
}
mVertexDeclDirty = false;
}
}示例2: SimpleRenderable
SurfacePatchRenderable::SurfacePatchRenderable() : SimpleRenderable()
{
// Set up what we can of the vertex data
mRenderOp.vertexData = new VertexData();
mRenderOp.vertexData->vertexStart = 0;
mRenderOp.vertexData->vertexCount = 0;
mRenderOp.operationType = RenderOperation::OT_TRIANGLE_LIST;
// Set up what we can of the index data
mRenderOp.indexData = new IndexData();
mRenderOp.useIndexes = true;
mRenderOp.indexData->indexStart = 0;
mRenderOp.indexData->indexCount = 0;
// Set up the vertex declaration
VertexDeclaration *decl = mRenderOp.vertexData->vertexDeclaration;
decl->removeAllElements();
decl->addElement(0, 0, VET_FLOAT3, VES_POSITION);
decl->addElement(0, 3 * sizeof(float), VET_FLOAT3, VES_NORMAL);
decl->addElement(0, 6 * sizeof(float), VET_FLOAT3, VES_TEXTURE_COORDINATES);
decl->addElement(0, 9 * sizeof(float), VET_FLOAT3, VES_TEXTURE_COORDINATES, 1);
