Detailed Description

Uses a VctVoxelizer to convert a single mesh made up of triangles into a voxel 3D texture representation.

This cache can be shared by multiple users (e.g. VctImageVoxelizer)

Member Function Documentation

addMeshToCache()

const VoxelizedMesh& Ogre::VoxelizedMeshCache::addMeshToCache	(	const MeshPtr &	mesh,
		SceneManager *	sceneManager,
		RenderSystem *	renderSystem,
		HlmsManager *	hlmsManager,
		const Item *	refItem
	)

addMeshToCache Checks if the mesh is already cached.

If it's not, it gets voxelized.

Parameters

mesh	Mesh to voxelize
sceneManager	We need it to temporarily create an Item
refItem	Reference Item in case we need to copy its materials. Can be nullptr

Returns

Entry to VoxelizedMesh in cache

getBlankEmissive()

TextureGpu* Ogre::VoxelizedMeshCache::getBlankEmissive ( )

inline

setCacheResolution()

void Ogre::VoxelizedMeshCache::setCacheResolution	(	uint32	width,
		uint32	height,
		uint32	depth,
		uint32	maxWidth,
		uint32	maxHeight,
		uint32	maxDepth,
		const Ogre::Vector3 &	dimension
	)

setCacheResolution When building the mesh cache, meshes must be voxelized at some arbitrary resolution This function lets you specify how many voxels per volume in units.

e.g. if you call

imageVoxelizer->setCacheResolution( 32u, 32u, 32u, maxWidth, maxHeight, maxDepth
                                    Ogre::Vector3( 1.0f, 1.0f, 1.0f ) );

And the mesh AABB is 2x2x2 in units, then we will voxelize at 64x64x64 voxels (unless this resolution exceeds maxWidth/maxHeight/maxDepth)

Remarks

This setting can be changed individually for each mesh. Call it as often as you need. e.g. a literal cube mesh only needs 1x1x1 of resolution.

Parameters

width	The width in pixels per dimension.x in units i.e. the width / dimension.x
height	The height in pixels per dimension.y in units i.e. the height / dimension.y
depth	The height in pixels per dimension.z in units i.e. the depth / dimension.z
maxWidth	Width can never exceed this value
maxHeight	Height can never exceed this value
maxDepth	Depth can never exceed this value
dimension	Units to cover (see previous parameters)

Member Data Documentation

mGlslTexUnits

FastArray<int32> Ogre::VoxelizedMeshCache::mGlslTexUnits

The number of texture units GL can handle may exceed the hard limit in ShaderParams::ManualParam::dataBytes so we need to use EX and store the data here.
