C++ (Cpp) frustumCull Examples

Example #1

File: graphics_gl3v.cpp Project: JanneSalokoski/vdrift

// if frustum is NULL, don't do frustum or contribution culling
void GraphicsGL3::AssembleDrawList(const std::vector <Drawable*> & drawables, std::vector <RenderModelExt*> & out, Frustum * frustum, const Vec3 & camPos)
{
    if (frustum && enableContributionCull)
    {
        for (std::vector <Drawable*>::const_iterator i = drawables.begin(); i != drawables.end(); i++)
        {
            if (!frustumCull(*i, *frustum) && !contributionCull(*i, camPos))
                out.push_back(&(*i)->GenRenderModelData(stringMap));
        }
    }
    else if (frustum)
    {
        for (std::vector <Drawable*>::const_iterator i = drawables.begin(); i != drawables.end(); i++)
        {
            if (!frustumCull(*i, *frustum))
                out.push_back(&(*i)->GenRenderModelData(stringMap));
        }

        {
            out.push_back(&(*i)->GenRenderModelData(stringMap));
