示例1:
VertexBuffer *SRPWindows::CreateVertexBuffer(const Vector2 &vPosition, const Vector2 &vImageSize)
{
// lets create a vertex buffer
VertexBuffer *pVertexBuffer = m_pCurrentRenderer->CreateVertexBuffer();
if (pVertexBuffer)
{
// setup and allocate the vertex buffer
pVertexBuffer->AddVertexAttribute(VertexBuffer::Position, 0, VertexBuffer::Float2);
pVertexBuffer->AddVertexAttribute(VertexBuffer::TexCoord, 0, VertexBuffer::Float2);
pVertexBuffer->Allocate(4, Usage::WriteOnly);
// fill the vertex buffer
UpdateVertexBuffer(pVertexBuffer, vPosition, vImageSize);
// return the created vertex buffer
return pVertexBuffer;
}
else
{
// something when wrong so we return nothing
return nullptr;
}
