simvx.graphics.renderer.render_pass

RenderPass base class and FrameContext — foundation for the render graph.

RenderPass is a concrete base class with no-op defaults (not abc.ABC) to avoid ABC construction overhead and clutter. Subclasses override what they need.

Module Contents

Classes

FrameContext	Per-frame state passed to render passes during record().
RenderPass	Base class for a single render pass. Subclasses override setup/record/resize/destroy.

class simvx.graphics.renderer.render_pass.FrameContext

Per-frame state passed to render passes during record().

Built once per frame by ForwardRenderer, then passed to every pass. Packs all per-frame state so passes don’t chain through engine attributes.

class simvx.graphics.renderer.render_pass.RenderPass

Base class for a single render pass. Subclasses override setup/record/resize/destroy.

Class attributes (override in subclasses): name: Unique identifier, e.g. “ssao”. stage: “pre_render” or “render” — controls which graph phase runs this pass. inputs: Resource names consumed, e.g. (“hdr_depth”,). outputs: Resource names produced, e.g. (“ao_texture”,).

setup(ctx: simvx.graphics.renderer.render_context.RenderContext) → None

Initialise GPU resources. Called once at renderer setup time.

resize(width: int, height: int) → None

Recreate resolution-dependent resources.

record(cmd: Any, frame: simvx.graphics.renderer.render_pass.FrameContext) → None

Record GPU commands for this pass. Called every frame by the RenderGraph.

destroy() → None

Release all GPU resources.
