示例1:
bool D3DVertexBuffer::create(const VertexLayout& layout, int length, int usage)
{
mStride = layout.getStride();
D3D11_BUFFER_DESC desc = {0};
desc.ByteWidth = mStride * length;
desc.Usage = D3D11_USAGE_DYNAMIC;
desc.BindFlags = D3D11_BIND_VERTEX_BUFFER;
desc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE;
desc.MiscFlags = 0;
desc.StructureByteStride = 0;
HRESULT hr = mDevice.getDevice().CreateBuffer(&desc, NULL, &mpBuffer);
if ( FAILED(hr) )
return false;
return true;
}示例2: initialize
void Vao::initialize(RenderState& rs, ShaderProgram& _program, const VertexOffsets& _vertexOffsets,
VertexLayout& _layout, GLuint _vertexBuffer, GLuint _indexBuffer) {
m_glVAOs.resize(_vertexOffsets.size());
GL::genVertexArrays(m_glVAOs.size(), m_glVAOs.data());
fastmap<std::string, GLuint> locations;
// FIXME (use a bindAttrib instead of getLocation) to make those locations shader independent
for (auto& attrib : _layout.getAttribs()) {
GLint location = _program.getAttribLocation(attrib.name);
locations[attrib.name] = location;
}
rs.vertexBuffer(_vertexBuffer);
int vertexOffset = 0;
for (size_t i = 0; i < _vertexOffsets.size(); ++i) {
auto vertexIndexOffset = _vertexOffsets[i];
int nVerts = vertexIndexOffset.second;
GL::bindVertexArray(m_glVAOs[i]);
// ELEMENT_ARRAY_BUFFER must be bound after bindVertexArray to be used by VAO
if (_indexBuffer != 0) {
rs.indexBufferUnset(_indexBuffer);
rs.indexBuffer(_indexBuffer);
}
// Enable vertex layout on the specified locations
_layout.enable(locations, vertexOffset * _layout.getStride());
vertexOffset += nVerts;
