This ticket gives an overview of the tasks that need to be done for the workbench engine.

UI Changes

• Each 3d view will have a location where the Viewpoint (Camera, Front, Side etc), Draw mode and Overlays can be selected

Draw modes

• Each render engine should be able to register their own set of draw modes.
• User should be able to select an draw mode. from the overlay render engine, workbench render engine
• When a user selects a draw mode the draw manager will enable the corresponding draw engine.
• Inside the draw mode selection menu the active draw mode can render its settings. [related to D834]

Overlay modes

• Users should be able to activate/inactivate an overlay.
• Only relevant overlay's for the workspace edit mode are selectable by the user (poll function)
• Active overlays are stored with the current workspace edit mode. Switching workspace edit modes will change the active overlays
• A user should be able to turn off/on the overlay render engine. (simulate render only)
• the active mode can also add an overlay that the users can enable/disable (floor)

Workbench Render Engine

The mission of the workbench render engine is to be the fastest render engine as possible.

Shading mode

• Silhouette drawing mode: The object/materials is rendered in a single emission color
• Solid drawing mode: The object is rendered using a diffuse shared with a constant color
  • All objects will use the same diffuse settings.
• Textured drawing mode?: Currently unclear if this will be the responsibility of the Workbench engine as it doesn't know about the used texture coordinates.
• drawing object smoke

Lighting options

• Studio lighting: a set of static lights will be used for highlights and shadows, The lights are parented to the viewing point. We will render these lights to a spherical texture and use the viewpoint normal to pick the highlight color.
  • Users should be able to change the static lighting setup.

Background

• HDRI
• Color

Floor

• Will render a reflective floor beneath the model.
  • Base Color
  • Roughness

F12-rendering

• Connect F12 rendering

Note: For scene lighting should we use the scene render engine?

Overlay Render Engine

• 3 types of wireframe drawing mode (front, front+back, tessellated)
• Texture drawing mode
  • The texture of the selected texture node of the material will be rendered.
    • The used texture coordinates have to be determined from the scene render engine. So we need go into this design...
• MotionTrail overlay: will draw the motion trails of the bones of the current object. The motion trails are baked.
• XRay
• Image (connected to empties or viewpoint)
• Bounding Box
