[Solved in trunk] CMeshManipulator recalculateNormals 32bit

[FreeFrags]

I have a DynamicMeshBuffer which has the vertex and index type set to irr::video::EIT_32BIT.

Im trying to do a CMeshManipulator::recalculateNormals on a the buffer. Which means this function is called:

Code: Select all

void CMeshManipulator::recalculateNormals(IMeshBuffer* buffer, bool smooth, bool angleWeighted) const
{
    if (!buffer)
        return;
 
    const u32 vtxcnt = buffer->getVertexCount();
    const u32 idxcnt = buffer->getIndexCount();
    const u16* idx = buffer->getIndices();

now i believe this line is not correct in this case (using a 16 bit index type its fine)

Code: Select all

const u16* idx = buffer->getIndices();

This calls the following function in IDynamicMeshBuffer:

Code: Select all

virtual const u16* getIndices() const
        {
            return (u16*)getIndexBuffer().getData();
        }

But since i set my index type to 32 bit i think we have an issue here.

Im using 1.7.3

Yes, we've updated several of those methods to xsupport 32bit indices in recent SVN versions. Not sure, though, which functions did not get an update.

Thanks for your reply I checked the trunk and applied copied the patch of the following function and it works

Code: Select all

void CMeshManipulator::recalculateNormals(IMeshBuffer* buffer, bool smooth, bool angleWeighted) const
