Processing of Models with Gamma Ray: Some Useful Tips
If you want to use the rendering program Gamma Ray to process your models further, you should take the following information into account:
- When using the lamps provided by the Lighting toolbar , the luminous intensity of all lamps and spotlights should together not be more than 1. 0.5 is frequently sufficient!
- Create reflecting side and rear walls and also roof and floor panel (as a very thin cuboid). This provides a high number of reflections.
- Assign sub-parts to a 3-D main part. This enables differently coloured or differently patterned surfaces to be created (different veneers, colour layers and so on).
- Define the Limiting angle for shading for each part of the drawing. Curved surfaces may have disturbing colour differences at the polyhedral edges. For all edges at which the adjoining surfaces form an angle smaller than the specified edge limiting angle, a correction is performed, enabling the edges to look "filleted".
- You use the Colour Editor to define properties such as glossiness and transparency.
- The GammaRay tool enables you to create files in the TIF, .TGA, .BMP and .JPEG format as well as videos.
- Please also note the Surface approximation function that you access via Drawing > Properties > Attr.
. Use this function to determine the number of polygon points for 3-D quadrants. This setting is, for instance, used for polyhedron approximations and the shading of 3-D models. The higher the value, the more precise will be the shading. However, please remember that the file size will also increase!
