class mrpt::opengl::CSkyBox

Overview

A Sky Box: 6 textures that are always rendered at “infinity” to give the impression of the scene to be much larger.

Refer to example Example: opengl_skybox_example

Methods

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:

DefaultShaderID

virtual void freeOpenGLResources()

Free opengl buffers.

virtual void initializeTextures() const

Initializes all textures (loads them into opengl memory).

void assignImage(const CUBE_TEXTURE_FACE face, const mrpt::img::CImage& img)

Assigns a texture.

It is mandatory to assign all 6 faces before initializing/rendering the texture.

Images are copied, the original ones can be deleted.

virtual auto internalBoundingBoxLocal() const

In this class, returns a fixed box (max,max,max), (-max,-max,-max).

virtual bool cullElegible() const

Return false if this object should never be checked for being culled out (=not rendered if its bbox are out of the screen limits).

For example, skyboxes or other special effects.
