Functions

bindBuffer

open fun bindBuffer(dc: DrawContext): Boolean

bindBufferAs

open fun bindBufferAs(dc: DrawContext, otherTarget: Int): Boolean

Bind this buffer to a target other than target. Same buffer storage, different binding point — used by callers that pack vertices + indices (+ batchIds) into a single buffer and bind it to both GL_ARRAY_BUFFER and GL_ELEMENT_ARRAY_BUFFER.

isLoaded

fun isLoaded(): Boolean

True once the GL buffer object exists and has been uploaded (so bindBuffer will succeed). A non-null but not-yet-loaded buffer means an upload is still queued.

loadBuffer

open fun loadBuffer(dc: DrawContext, array: NumericArray)

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.
