RedSDK Global Environments
RedSDK supports three global Environment types:
...
- File Name - file and location of the image file if image is selected.
- U Wrap Mode –U wrap mode of the source image.
- REPEAT – Repeat the texture pattern out of the texture's limits.
- MIRRORED REPEAT – Repeat the texture pattern with an inversion of the texture out of the texture's limits.
- CLAMP – The texture sampling result is zero outside of the texture's limits.
- CLAMP TO_EDGE – The texture sampling results remain slightly inside the texture when it's out of the texture's limits.
- CLAMP TO_BORDER – The texture sampling results are set to the texture's border color when it's out of the texture's limits.
- V Wrap Mode –V wrap mode of the source image.
- REPEAT – Repeat the texture pattern out of the texture's limits.
- MIRRORED REPEAT – Repeat the texture pattern with an inversion of the texture out of the texture's limits.
- CLAMP – The texture sampling result is zero outside of the texture's limits.
- CLAMP TO EDGE – The texture sampling results remain slightly inside the texture when it's out of the texture's limits.
- CLAMP TO BORDER – The texture sampling results are set to the texture's border color when it's out of the texture's limits.
Physical Sky
- Convert emitter units to meters - Scaling factor to convert scene units to meters.
- Extra scale - a multiplier applied to the scaling.
- View height in meters - Height of the viewer in atmosphere in meters (0, +).
- Turbidity – The amount of molecules in the atmosphere (0, 100). The higher, the more foggy. Default value of 20 is good for European countries.
- Albedo – The amount of sun light reaching the ground which is reflected back to the sky per RGB color component [0, 1]. A default value of 0.3 per component is good.
- Aerosols Albedo – The amount of sun light reaching the aerosols which is reflected back to the sky [0, 1]. The light which is not reflected is absorbed by aerosols.
- Asymmetry Factor - Controls the anisotropy of the light reflection due to aerosols [-1, 1]. 0 is for fully isotropic aerosols, 1 is anisotropic (towards the viewer), -1 is anisotropic (towards the source).
- Sun Dir - Direction towards the sun (does not need to be a unit direction) from the center of the earth.
- Sun dir by geo-location - Set the suns location by the geo-location and time of the drawing.
- Sun Radius Scale - Sun radius scaling (set it to 1.0 to get the real sun size).
- Sun Intensity Multiplier - sun intensity multiplier (set it to 1.0 to get the real sun intensity).
- Moon Dir - direction towards the moon (does not need to be a unit direction) from the center of the earth.
- Moon dir by geo-location - Set the moons location by the geo-location and time of the drawing.
- Moon Radius Scale - Moon radius scaling (set it to 1.0 to get the real moon size).
- Moon Intensity Multiplier - moon intensity multiplier (set it to 1.0 to get the real moon intensity).
- Stars Intensity Multiplier - Stars intensity multiplier (set it to 1.0 to get the real stars intensities).
- Width - Width of the output texture. Must be a multiple of 2
- Saturation - saturation factor applied to the whole model. If saturation is set to 1.0, colors are returned as computed by the model. For other values, returned colors will look more greyish. The valid range of values is [0, 1].
- Sky Multiplier - Sky multiplier applied to each pixel in the texture. Set it to 1.0 to create a physically accurate texture of the sky. Lower values can be used to simulate the effect of clouds or environment on the sky intensity.
- Include sun - true to render the sun into the texture, false otherwise.
