Logging and renderer capabilities

module Cap: sig .. end

Renderer capabilities.

Render operations

val nop : Lit.op

nop is a render no-op, it has no effect on the renderer.

val op : ?count:int ->
       ?uniforms:Lit.Uniform.set -> ?tr:Gg.m4 -> Lit.effect -> Lit.prim -> Lit.op

op count uniforms tr e p is a render op. count defaults to 1. uniforms defaults to Lit.Uniform.empty, tr to M4.id.

val add_op : Lit.renderer -> Lit.op -> unit

add_op r o adds render operation o on r.

Screen geometry and projection

val size : Lit.renderer -> Gg.size2

val set_size : Lit.renderer -> Gg.size2 -> unit

val view : Lit.renderer -> Lit.View.t

val set_view : Lit.renderer -> Lit.View.t -> unit

Framebuffers

val fbuf : Lit.renderer -> Lit.fbuf

fbuf r is the framebuffer on which render ops are performed.

val set_fbuf : Lit.renderer -> Lit.fbuf -> unit

set_fbuf r fbuf sets the framebuffer to fbuf.

Rendering

val render : ?clear:bool -> Lit.renderer -> unit

render clear r renders the added operations. If clear is true (default) the current framebuffer is cleared before rendering.

Renderers

module Private: sig .. end

Private functions and types for implementing renderers.

module type T = sig .. end

The type for a renderer backend.

type t = Lit.renderer

The type for renderers.

val create : ?compiler_msg_parser:Log.compiler_msg_parser ->
       ?log:Log.t ->
       ?debug:bool -> size:Gg.size2 -> (module Lit.Renderer.T) -> Lit.renderer

creates size b creates a renderer with backend b. A valid OpenGL context is needed before calling this function.

val release : Lit.renderer -> unit

release r releases GPU resources associated to the renderer.
