Jonathan Posted February 28, 2014 Share Posted February 28, 2014 Any suggestions on how to create something like this? Imagine an animated spline growing from A to B (for example). I want to apply an animated colour texture (pre-rendered from audio reactive software) to the diffuse channel. The result should show the visualised audio in the full spline. The issue I cant yet figure out is how the texture can hold colour information from previous inputs to show the complete rhythm of audio. Any ideas?

Stephen Thomas Posted February 28, 2014 Share Posted February 28, 2014 Not sure if I'm understanding the full thing correctly, but couldn't you output a frame sequence and load in as per a normal bitmap? Link to comment Share on other sites More sharing options...
Jonathan Posted February 28, 2014 Author Share Posted February 28, 2014 Hi Stef, Mmm, that could definitely work although might require a pretty long bitmap. Would be great to have some sort of material 'memory' functionality in Max. Link to comment Share on other sites More sharing options...
Jonathan Posted February 28, 2014 Author Share Posted February 28, 2014 An analogy might be snake skin with banding determined by musical beats in a bar. Link to comment Share on other sites More sharing options...
Stephen Thomas Posted February 28, 2014 Share Posted February 28, 2014 So at the moment it's a short section where the pattern scrolls across, is that right? Finding it a bit hard to picture Link to comment Share on other sites More sharing options...
Jonathan Posted February 28, 2014 Author Share Posted February 28, 2014 Yep, thats about it Link to comment Share on other sites More sharing options...
Stephen Thomas Posted February 28, 2014 Share Posted February 28, 2014 So, once the beat/spline moves on the previous section's texture remains static? Link to comment Share on other sites More sharing options...
Jonathan Posted February 28, 2014 Author Share Posted February 28, 2014 Exactly, how can the previous texture (colour) remain? Imagine the entire snake represents a song Link to comment Share on other sites More sharing options...
Stephen Thomas Posted February 28, 2014 Share Posted February 28, 2014 I think you're going to have to break your spline and animation down into matching chunks. With the bitmap sequence approach you have the option to choose from loop, ping-pong and hold under the time tab. I guess hold is what you're after. Then have a multi-sub material containing all the chunks and set the start frame for each sub-anim to start when it's time for that segment to grow. Something like that anyway!

Jonathan Posted February 28, 2014 Author Share Posted February 28, 2014 Sounds like a way to go. A 4 minute audio track represents 7200 frames with each frame represented by a single pixel, so a 7200px x 1px wide image. Thanks for your time Stef!

Crazy Homeless Guy Posted March 1, 2014 Share Posted March 1, 2014 Pictures or screen caps would help. Link to comment Share on other sites More sharing options...
Stephen Thomas Posted March 1, 2014 Share Posted March 1, 2014 Pictures or screen caps would help. Yes. It's a very visual problem with no visuals! Difficult to advise. Sent from my HTC One mini using Tapatalk Link to comment Share on other sites More sharing options...
Jonathan Posted March 1, 2014 Author Share Posted March 1, 2014 Agreed! So, here's something close to what Im rambling on about from Universal Everything: The material here however is not responsive to audio. Does that help? Link to comment Share on other sites More sharing options...
Stephen Thomas Posted May 10, 2014 Share Posted May 10, 2014 Out of curiosity, did you get there in the end Jonathan? Sent from my HTC One mini using Tapatalk Link to comment Share on other sites More sharing options...
Jonathan Posted May 13, 2014 Author Share Posted May 13, 2014 Still on-going! Hope to make some progress soon... Link to comment Share on other sites More sharing options...
