Methods
virtual shader_list_t requiredShaders() const
Returns the ID of the OpenGL shader program required to render this class.
See also:
virtual void render(const RenderContext& rc) const
Implements the rendering of 3D objects in each class derived from CRenderizable.
This can be called more than once (one per required shader program) if the object registered several shaders.
See also:
virtual void renderUpdateBuffers() const
Called whenever m_outdatedBuffers is true: used to re-generate OpenGL vertex buffers, etc.
before they are sent for rendering in render()
virtual void onUpdateBuffers_TexturedTriangles() = 0
Must be implemented in derived classes to update the geometric entities to be drawn in “m_*_buffer” fields.
virtual void freeOpenGLResources()
Free opengl buffers.
void assignImage(const mrpt::img::CImage& img)
Assigns a texture image, and disable transparency.
Images are copied, the original ones can be deleted.
