Functions

attachTexture

fun attachTexture(dc: DrawContext, texture: Texture, attachment: Int, textarget: Int = GL_TEXTURE_2D): Boolean

Attach a texture to the given FBO attachment point. The default textarget is GL_TEXTURE_2D; pass a specific cube-map face target (e.g. GL_TEXTURE_CUBE_MAP_POSITIVE_X) to attach a face of a cube-map texture. The same cube-map texture can be re-attached to the same FBO multiple times with different faces to render into all six faces of one cube map without rebinding the FBO.

bindFramebuffer

fun bindFramebuffer(dc: DrawContext): Boolean

getAttachedTexture

fun getAttachedTexture(attachment: Int): Texture

getFramebufferName

fun getFramebufferName(dc: DrawContext): KglFramebuffer

Underlying GL framebuffer name. Created lazily on first access.

isFramebufferComplete

fun isFramebufferComplete(dc: DrawContext): Boolean

release

open override fun release(dc: DrawContext)

Frees any resources associated with this instance. After this method returns the rendering resource is invalid, and any associated GL object is deleted.
