Details

    • Technical task

    • P1: Critical
    • 6.0
    • Qt RHI, Quick: 3D
    • None

    Description

      * Blending. Alpha pass. [DONE]

* Port the glsllib snippets (default material). Uniforms have to (also) be declared in metadata now. [DONE]

* Texture support: QTBUG-81656 [DONE]

* Built-in shader code handling infrastructure (non-material shaders, these should be offline processed into .qsb) [DONE]

* Shadows QTBUG-81555 [DONE]
	- directional light shadows, plus blur passes [DONE]
	- point light shadows (omnidirectional shadow map, with cubemap texture) plus blur passes [DONE]

* Depth pre-pass QTBUG-81933 [DONE]

* Skybox QTBUG-81685 [DONE]

* SSAO QTBUG-81999 [DONE]

* Image based lighting QTBUG-82001 [DONE]

* light probes [DONE]
	- HDR prefilter on CPU and via compute [DONE]
        - Missing: Per-material light probes [DONE]

* Principled material QTBUG-81684 [DONE]

* View3D.renderMode other than Underlay and Overlay: Offscreen [DONE]
 
* MSAA. Offscreen and Underlay/Overlay View3Ds need different handling. QTBUG-82130 [DONE]

* SSAA (for Offscreen only) - QTBUG-82174 [DONE]

* Multiple View3D items in one scene (broken in the initial prototype) [DONE]

* View3D.renderMode == Inline QTBUG-82793

* Investigate the need for scissoring (??)

* Texture.sourceItem: 2D item layer (texture) in the 3D scene QTBUG-82927

* Custom materials QTBUG-82245 Initial port is [DONE] Advanced features are in QTBUG-82790 and are to be tackled separately.
        - Diverges from the default material based code path in many places. Some uniform data is handled differently with custom materials. (shadow, SSAO, etc. is handled differently - all these need to be re-investigated in combination with custom materials)
	- Vulkan-style GLSL + metadata as the input.
	- Check the feature set. Unclear if we want/can have all.

* New postprocessing effect system QTBUG-82247
        - Similar challenges as with custom material.

* Progressive AA and Temporal AA [DONE]

* Offline material shader generation solution. See QTBUG-78135. WILL NOT BE HANDLED AS PART OF THIS TASK.
