Hello, thanks for the tutorials~ May I ask how to give a color ramp based on the distance from the centre of a vdb sphere, and also adjust the alpha of the sphere so that the color could be visualized~ Hope you could give some advices or make a video? Thanks so much!
Hello Catherine, in SOPs it would be attribute from volume and a color node using ramp from attribute. In (COP) VOPs it would be volume sample and a ramp parameter set to color.
@@KonstantinMagnus Thanks! I tried to send email for more help, but the system seemed to be not supportive. I may have to keep asking here, sorry~ I am still newbie in Houdini, so I am not sure that by using volume and color node, what parameters I need to manipulate to achieve the effect. Also, does using volume node mean that I do not need to use vdbfrompoly to have my sphere solid? In detail, what I want to simulate is a bit science-based. I have got my data, and I would like to make a droplet with ramp color from dark to light based on different concentration data and corresponding distance from the center data I have. Many thanks in advance! Hope you could help me~
@@catherinekan3610 It's best you come over to the odforce Houdini forums. There is plenty of space and people to discuss your issues with image uploads and so on. : )
final result is very beautiful, very interesting, complicate, but very good. thank you. I would like to bring this to a color gamut form, if i can get my understanding to it. Great work, thank you.
love this, great to see some COPs
