示例1: RunVertices
int RunVertices(int vtx_attr_group, int primitive, int count, DataReader src, bool skip_drawing,
bool is_preprocess)
{
if (!count)
return 0;
VertexLoaderBase* loader = RefreshLoader(vtx_attr_group, is_preprocess);
int size = count * loader->m_VertexSize;
if ((int)src.size() < size)
return -1;
if (skip_drawing || is_preprocess)
return size;
// If the native vertex format changed, force a flush.
if (loader->m_native_vertex_format != s_current_vtx_fmt ||
loader->m_native_components != g_current_components)
{
VertexManagerBase::Flush();
}
s_current_vtx_fmt = loader->m_native_vertex_format;
g_current_components = loader->m_native_components;
// if cull mode is CULL_ALL, tell VertexManager to skip triangles and quads.
// They still need to go through vertex loading, because we need to calculate a zfreeze refrence
// slope.
bool cullall = (bpmem.genMode.cullmode == GenMode::CULL_ALL && primitive < 5);
DataReader dst = VertexManagerBase::PrepareForAdditionalData(
primitive, count, loader->m_native_vtx_decl.stride, cullall);
