Detailed Description

This is ogre-procedural's temporary mesh buffer.

It stores all the info needed to build an Ogre Mesh, yet is intented to be more flexible, since there is no link towards hardware.

◆ endSection()

void Procedural::TriangleBuffer::endSection ( Section & section )

References Procedural::TriangleBuffer::Section::mLastIndex, Procedural::TriangleBuffer::Section::mLastVertex, and Procedural::TriangleBuffer::Section::mSectionName.

◆ estimateIndexCount()

void Procedural::TriangleBuffer::estimateIndexCount ( unsigned int indexCount )

Gives an estimation of the number of indices needed for this triangle buffer.

If this function is called several times, it means an extra indices count, not an absolute measure.
