Mars

Unread postby Krolik » Thu Jun 18, 2015 3:57 pm

Hey all. I am doing a little Mars project to test Clarisse. What I did for these images is take the MOLA data from NASA and importing it into zbrush for displacement and painting, then export a 100 million poly mesh. The MOLA data is 46k x 23k. In Houdini I converted it to an alembic for better performance. Then I created a colored atmosphere with VDBs. The alembic contains around 4 GB and the VDB around 6 GB. I also used the MOLA data as a bumpmap. No problem for Clarisse, working is smooth and rendering is fast.
Coming up is more VDB dustclouds and closeups of the surface. I will post a video as well.

Looks great! I like the little volumetric shadows in the last image.

I love the features of the shadow of what seems to be the Olympus Mons. Great work!

Nice shots! The surface volumes are looking good. Funny, we used the same map data, nearly the same shot/angles when working on Cosmos....but we were using maya and modo at the time...so, working with the large maps in the scene was not fast like in Clarisse.

Thanks,

Here is an animated version:

I think the best thing is that it is always smooth to work with. No stuttering or beachballs. If I preview the same scene in Houdini with openGL the machine crashes and reboots. And it is powerful to just import a highres zbrush file without any polyreduce is a huge time saver. reducing a 100 mill polys can take up to an hour.
I loved the cosmos series, some really great work there.

Thanks. I actually did a couple more of these. Its a zbrush mesh of about 100 million polys and a huge amount of mari textures and lots of volumes from Houdini. Rendertimes is about 20 mins per frame. I only have one machine and wanted to render a sequence. If I try to open up the same stuff in any other program, including Houdini, my machine crashes and reboots. Lots of power in Clarisse.

beautiful work! Playing with atmospheres myself, would be interested to know more about your vdb/volumetric workflow.

problems with a click. The workflow is pretty simple. It's just a Houdini/Clarisse setup. Everything I can do in Houdini exports without any (almost) problem.
