◆ MODEL_3D()

MODEL_3D::MODEL_3D	(	const S3DMODEL &	a3DModel,
		MATERIAL_MODE	aMaterialMode
	)

Load a 3D model.

Note: This must be called inside a gl context.

Parameters

a3DModel	a 3d model data to load.
aMaterialMode	a mode to render the materials of the model.

WARNING: Horrible hack here! Somehow, buffer values are being shared between pcbnew and the 3d viewer, which then frees the buffer, resulting in errors in pcbnew. To resolve this temporarily, we generate extra buffers in 3dviewer and use the higher numbers. These are freed on close. todo: Correctly separate the OpenGL contexts to prevent overlapping buffer vals
