VboMesh /

Constructs a VAO (in the currently bound VAO) that matches this to GlslProg shader , overriding the mapping of a geom::Attrib to a named attribute via the 'a attributeMapping std::map.

Returns the number of vertices in the mesh.

Returns the number of indices for indexed geometry, otherwise 0.

Returns the primitive type, such as GL_TRIANGLES, GL_TRIANGLE_STRIP, etc.

Returns the data type of the indices contained in index vbo; either GL_UNSIGNED_SHORT or GL_UNSIGNED_INT.

Returns 0 if attr is not present.

Returns AttribSet of geom::Attribs present in the VboMesh .

Returns the VBO containing the indices of the mesh, or a NULL for non-indexed geometry.

Updates internal vertex count to reflect an external change to underlying VBOs. Does NOT reallocate or modify storage.

Updates internal index count to reflect an external change to underlying VBOs. Does NOT reallocate or modify storage.

Builds and returns a vector of VboRefs for the vertex data of the mesh.

Returns the vector of pairs of (BufferLayout,VboRef) for the vertex data of the mesh.

Adds a new VBO (paired with its geom::BufferLayout ) to the VboMesh .

Returns a pair<geom::BufferLayout,VboRef>* that corresponds to attrib . Returns nullptr if not found.

Fails with an error on ES 2 platforms which don't support buffer mapping when used with interleaved buffers. When multiple attributes are stored interleaved in a single VBO, this can be less efficient than calling mapAttrib*() or manipulating the VBO directly.

Must call unmap() on the result. Throws ExcMissingAttrib if the VboMesh doesn't contain attr .

Issues a glDraw* call, but without binding a VAO or sending shader vars. Consider gl::draw( VboMeshRef ) instead. Knows whether to call glDrawArrays or glDrawElements.

Returns a geom::Source which references 'this'. Inefficient - primarily useful for debugging. The returned geom::SourceRef should not outlive 'this' (not a shared_ptr).

Copies indices to dest . Requires dest to provide storage for getNumIndices() indices. Inefficient - primarily useful for debugging.

Echos all vertex data in range [ startIndex , endIndex ) to os . Inefficient - primarily useful for debugging.

Echos all vertex data for the indices in range [ startIndex , endIndex ) to os . No-op for non-indexed geometry. Inefficient - primarily useful for debugging.

Creates a VboMesh which represents the geom::Source source . Layout is derived from the contents of source .

Creates a VboMesh which represents the geom::Source source using layout .

Creates a VboMesh which represents the geom::Source source using 1 or more VboMesh::Layouts for vertex data.

Creates a VboMesh which represents the geom::Source source using 1 or more Vbo/VboMesh::Layout pairs. A null VboRef requests allocation.

Creates a VboMesh which represents the user's vertex buffer objects. Allows optional indexVbo to enable indexed vertices; creates a static index VBO if none provided.
