| Summary | 0026070: Ray tracing with reflections is poor on rotated presentation | ||||
| Description | The problem is discovered in Windows version of CAD Assistant, on sample model cad.brep: if ray tracing and reflections is enabled, it is shown with artifacts, looking like reflections of non-existent objects. Note that the model consists of solid and set of wires, and uses location assigned to these in order to have faces forming "CAD" letters visible when the model is opened with default view settings. Use script in Steps to Reproduce to see the problem (reflections are present on outer surfaces of the shape) in DRAW | ||||
| Steps To Reproduce | source samples/tcl/cad.tcl vrenderparams -rayTrace -reflections vlocrotate res 0 0 0 0 0 1 180 vfit | ||||
| Additional information and documentation updates | Generation of secondary rays was incorrect in case of non-identity viewer transformation applied to AIS shape. As a result, global illumination effects (like shadows, reflections, and refractions) were also incorrect. This patch fixes the above problems by handling such transformations in ray-tracing shaders. | ||||
