SetTexturePixel
SetTexturePixel
Sets the RGBA values of a single texture pixel. The custom channel is optimized for speed in continuous mode (e.g. For-Loops). Update rates of up to 1.4 Mpixel/sec have been reached. The 5.0 version allows additional fill and save operations.
See Quest3D forum page for further description. Access to all trial ressources [here]. Available for 4.3.2 and 5.0 (x64). Read the manual pages.
Fees (in Euro): Full version 79.- € + Taxes, license agreement. Send me an e-mail to proceed.
Comparison LDR/HDR

HDR (Floating Point) |

| 64x64 intensity steps mapped to 8 Bit leads to Banding | 64x64 intensity steps mapped to Real omits banding |
 |

| All intensity levels confined to LDR cage | Intensities outside LDR cage (Note: LDR rendering clips to white) |
Experiment to show the difference between LDR and HDR. A wedge is produced with SetTexturePixel. The resulting texture is 64 x 64 in size. Intensities run betweein 0 and 1.0. For HDR, an optional offset is added. Uses Texture2Heightmap plug-in to generate a 3D geometry. File: SetTexturePixel-HDR-Demo.cgr.
