| Summary | 0006082: Implement sorting of Interaction Stages | ||||
| Description | The game sorts bump/diffuse/specular stages to process them in a certain order when drawing interaction passes. DarkRadiant only supports one interaction pass per material right now. | ||||
| Additional Information | See DarkRadiant's current implementation in OpenGLShader::constructLightingPassesFromMaterial() See game code: Material::SortInteractionStages() and InteractionStage::DrawInteractions() Stages are sorted bumps first, then diffuses, then speculars. When drawing interactions a new draw call is queued/submitted for every new stage whose type is already active in that interaction, plus the round-up draw call. For example, the sorted stage setup Bump Diffuse1 Diffuse2 Specular will result in the following three draw calls: Bump + Diffuse1 + _black Bump + Diffuse2 + _black Bump + Diffuse2 + Specular The second draw call is kind of unintuitive, it is triggered when encountering the specular map (with the _black specular already in place, the specular counts as "second" stage of that type). | ||||

An example material for testing: textures/glass/two_diffuse_one_bump_one_spec { diffusemap textures/darkmod/glass/victorian01_d { blend diffusemap map textures/darkmod/decals/graffiti/food_not_works rgb 0.7 } bumpmap textures/darkmod/glass/dull_opaque01_local specularmap textures/darkmod/metal/flat/simple_grey01_s } |

DarkRadiant: master 98473c29 27.08.2022 13:45 Details Diff |
0006082: Handle interaction stages in a similar way as the TDM engine is doing it. Multiple interaction stages are sorted and grouped very late (right before the draw calls) in a single loop. Imply that any material without bump stage has is rendered with an implicit _flat map. |
