Detailed Description

Component that provide Mesh handling and rendering.

Member Function Documentation

addMaterial()

void oe::render::MeshRenderer::addMaterial ( bool assign_to_primitives = false )

inline

Add a new material.

Add the material then init the list (by default the material will not be applied to any primitives)

Parameters

assign_to_primitives

Assign the newly created material to all primitives

Note

No material deletion method available because removal might break the ids on user side

(you can still manipulate primitives_by_material and materials yourself)

fillRenderCommands()

bool oe::render::MeshRenderer::fillRenderCommands ( const scene::Camera & camera, const bool is_blending_pass, std::vector< render::DrawCommand > & result )

inline

Generate a list of {primitives, Material*} to render this mesh.

Returns

Does this mesh need to be rendered

fillShader()

void oe::render::MeshRenderer::fillShader ( ShaderBase * shader, const oe::scene::Camera & camera )

inline

Send shader uniforms related to this mesh.

Note

At this point the mesh is considered to be ready to be drawn, no need to add any checks :)

Member Data Documentation

materials

std::vector<scene::Material> oe::render::MeshRenderer::materials

Distinct list of materials applied on this mesh.

See also

primitives_by_material to assign materials on primitives

primitives_by_material

std::vector<std::vector<bool> > oe::render::MeshRenderer::primitives_by_material

List to assign materials to primitives.

Keys are material ids (ie. position in materials list) and values are primitive flags (ie. true means the corresponding primitive will be drawn using the material)

Note

Primitives assigned to multiple materials will be drawn multiple times (to let use creative effects)
