00:07:28 OpenCl AMD R9 290x R9 390x

GPU Tile Path render, 250 Samples, 25 Frames. Sun turns 180° horizontal and 90° vertikal. Camera gain is animated too, because dusk and dawn are quite dark. Camera white balance would be a very appreciated enhancement. Dandelion-3.gif Or with all colors and 1000x1000 px. https://youtu.be/1IDNHWY9DM0

Actually, I was looking for an optimal openCL render for the completed wooden room. First, I used random sampler also in combination with denoiser or post processing without getting a useful result. Then I switched through all available samplers in luxcorerender addon looking for an appropriate solu...

In a next step I'm going to work out the colors of the petals.

One of my friends made an update of a 3D robot with a green laser for engraving wood, plastics or leather. It works well based on diffrent open source drivers and software. He sent me a picture showing the beam and its reflections through transparent, coated glasses. Give me a try, I said, I can sim...

Common dandelion's common flower has 3 to 7 layers of petals, with 24 to 36 petals in each layer. It's not really layers, I think it's maybe some parabolic spiral, like this Sunflower_spiral.png That's mine. 1.png They have 5 layers of 25 rectangular petals each, not so detailed though. Hi, wasd Th...

GPU tile path, 250 Samples, clamped

I did not expect how much time I had to spend to setup this scene. Some parts are revised several times before I could accept them. Finally I like the picture with its artificial look of this well known plant.

At the moment topic number one is glass' transparency. Again I don't understand the difference of a ray from different sources. There is obviously light from a source like point or sun or a scattered beam and there is another kind of light from HDRI or indirect light from an object made from matte o...

If one sets a glass cuboid in front of an objects so that one part of the object is covered by the cuboid and the other not one can expect part behind glass takes more time to be rendered. One can compare number of samples per pixel to get a similar pattern for an object aside or behind glass. The b...

This file renders pretty well: Glass Scatter Clear World.
This file renders strange: Glass and scattering beams.

Load the file and start the render.
