Constructor & Destructor Documentation

Mesh() [1/2]

template<typename SceneMeshType >

oe::render::Mesh::Mesh ( const SceneMeshType &  scene_mesh, bool  editable = false  )

inline

Construct a mesh from an existing scene mesh.

Parameters

scene_mesh
editable	Set to true to allow mesh buffer to be updated

Mesh() [2/2]

template<typename SceneMeshType >

oe::render::Mesh::Mesh ( const SceneMeshType &  , uint32_t  max_vertices_count, uint32_t  max_indices_count  )

inline

Allocate a mesh to be dynamically filled.

Note

SceneMeshType data not used its only used as mecanism to fetch vertices and indices types (to bypass template constructor call not available in C++)

Member Function Documentation

getRawBuffers()

std::pair< void *, void * > oe::render::Mesh::getRawBuffers ( )

inline

Get raw GPU buffers of the mesh (to write data)

Warning

Do not forget to release back the buffers by calling releaseRawBuffers after you write

Note

Advanced usage, not recommended to use

releaseRawBuffers()

void oe::render::Mesh::releaseRawBuffers ( )

inline

Release raw buffers got by getRawBuffers.

Note

Advanced usage, not recommended to use

render()

void oe::render::Mesh::render ( const std::vector< bool > &  activeprimitives, uint32_t  mode = default_mesh_rendering_mode  )

inline

Ask the GPU to render specific primitives of the mesh.

Parameters

activeprimitives	which primitives to render
mode	MeshDrawMode to specify how to render the mesh (default are triangles)

renderAll()

void oe::render::Mesh::renderAll ( uint32_t  mode = default_mesh_rendering_mode )

inline

Ask the GPU to render the complete mesh

Parameters

mode	MeshDrawMode to specify how to render the mesh (default are triangles)

renderArrays()

void oe::render::Mesh::renderArrays ( const uint32_t  count, const uint32_t  offset, uint32_t  mode  )

inline

Ask the GPU to render only the vertices (ignore primitive contents)

Parameters

offset	id of first vertex to draw
count	total vertices to draw
mode	MeshDrawMode to specify how to render the mesh (default are triangles)

renderElements()

void oe::render::Mesh::renderElements ( const uint32_t  count, const uint32_t  offset, const uint32_t  mode  )

inline

Ask the GPU to render only some indices (ignoring primitive contents)

Parameters

offset	id of first vertex to draw
count	total vertices to draw
mode	MeshDrawMode to specify how to render the mesh (default are triangles)

setIndicesData()

void oe::render::Mesh::setIndicesData ( const uint32_t  size, const void *  data, const uint32_t  offset = 0  )

inline

Partial update of indices buffer

setSubBufferData()

void oe::render::Mesh::setSubBufferData ( const uint32_t  size, const void *  data, const uint32_t  offset = 0  )

inline

Partial update of vertices buffer
