Hello, I understand that these tutorials were made for an ancient version of Houdini, but I suspect the L-System node hasn't changed too much in the meanwhile. I became a paid user of cmiVFX, but it seems the site became inoperative before I really had the chance to get too far into that course. All the courses on the site became unviewable, and any attempts to contact anyone responsible for keeping it working, failed for quite a few weeks, and so did the ones that Paypal made on my behalf, so I got a refund. The wish to see these tutorials still remains, though. Does anyone here have an idea about how to contact someone to get access to these videos, or the DVDs. As I understand, they have been released on DVDs. Perhaps someone could sell these to me if collecting dust somewhere not being used? Would really appreciate the advice. Any other suggestions for tutorials dealing with L-Systems, would be greatly appreciated as well. I have gone through the Pluralsight course, the Tyler Bay course, Ari Danesh First Steps video, have the digital version of the Algorithmic Beauty of Plants and am playing with the example files with L-systems (and wire solver) from the SideFX docs, and scanning this very site on this subject, but still, if there is a valuable compiled resource for learning the different methods of using this node (like the cmiVFX course seems to be), I'd be interested.
anicg posted a topic in EducationHi, I need to learn how to make this stuff: from the Houdini 18 presentation (min 11:58), this guy just draw a line and gets a tree. Anyone happy to teach how to make it? I'm not interested in getting a tool that does it, I need to learn how to create it. Thanks.
If you're interested, be sure to check out the course right here: http://bit.ly/2tEhWFN L-systems offer a great way of procedurally modeling geometry, and with these skills, you'll be able to create a wide variety of complex objects. If you've ever wanted to create foliage, complex fractal geometry, or spline-based models from scratch, then L-systems offers you a procedural way of doing so. Unlike many other tutorials, this course aims to address the topic in an easy-to-follow, technical, and artistic way. In addition to L-systems, you'll learn more about instancing and how to work efficiently with Houdini. We'll be rendering out millions of polygons with both Mantra and Redshift while aiming to optimize render times as much as possible. These optimizations are applicable across a wide variety of 3D topics. Large scale environment creation, destruction, crowds, and real-time render engines are all examples of other 3D topics which will benefit from this course. Thank you for watching!
Hi everyone, I am still working on a shot where trees bend due to a rocket exhaust. I have tried FEM but I think it will not do what I want (too 'chunky'). I would like to try the Wire solver. What I want is the trunk of the tree to bend very slightly, the branches to bend a bit more and the twigs to bend a twitch a lot - bend angle proportional to branch thickness, basically. How can I vary the wire deformer strength or bend angle along the length of the L-System branches? I suspect this is a VERY simple thing for a Houdini TD to do, but I am not sure how to approach it. Please help! I enclose a simple setup where I have a L-system, converted into a Wire sim, with a hard pin constraint on the base of the trunk and I made a Wind force pushing on it. Many thanks l-system_wire_test_02.hip
