Robert Posted September 11, 2014 Share Posted September 11, 2014 When I first saw your example I interpreted it as self shadowing so I went with that, the lesson learned should be similar . The first vopsop makes the deformations and the second creates the shadows. I gave the soft shadows a try but there is definitely something wrong there.

MrScienceOfficer Posted September 11, 2014 Share Posted September 11, 2014 That's really good, much cooler then what I had done. With the soft shadows, I really should of mentioned you (or at least my method) need a second vopsop. It was like four thirty in the morning I was way overtired but I couldn't sleep so I figured, Hey this would be a great time to make a vopsop challenge. Whole things kinda a haze now....

ioness Posted September 11, 2014 Share Posted September 11, 2014 Here is what I came up with, some things didn't work out as I wanted but anyways, here is the picture: Quote Link to comment Share on other sites More sharing options...
georgeivan Posted September 11, 2014 Share Posted September 11, 2014 (edited) Would be cool to close a challenge with a explanation of how the exercise its done ,just to make the thread more clean I end up last challenge with this But with a pc setup and captain posted another way with a near point setup. Thanks! Edited September 11, 2014 by georgeivan Quote Link to comment Share on other sites More sharing options...
wixman Posted September 11, 2014 Share Posted September 11, 2014 Here's my attempt. I used 3 seperate vop sops, but I could have probably reduced that.With one of them I setup lambertian shading (clamped dot product of surface normal with light ray), with the 2nd I setup up the shadow casting (intersect, using the vector from the light source to the point position), and with the 3rd I just did some smoothing/blurring with a point cloud.

nangu Posted September 11, 2014 Share Posted September 11, 2014 I'm sorry guys, I appreciate the excersices posted on this thread, but I can't keep up. The last two are difficult to figure out how to achieve the posted images without a little background or explanation. To be honest, I expected a learning curve which allow a noob like me to take some fundamentals and gradually learn how they meet together. At least, as georgeivan said before, a good explanation on how it was done will be very welcome before to move onto the next one. This is my attempt at the day 8 excercise. Thanks.

ioness Posted September 11, 2014 Share Posted September 11, 2014 (edited) I agree that the person who launched the exercice, once the next is started, explain or post his file which would allow the person who didn t find a solution to see how it was done. This way, they could progress and then try to do it again. Edited September 11, 2014 by ioness Quote Link to comment Share on other sites More sharing options...
Guest tar Posted September 11, 2014 Share Posted September 11, 2014 Would you say the trouble with learning VopSop is in general not having a solid grounding in maths i.e. trigonometry is a set of ratios, a matrix is used for affine transforms etc. Quote Link to comment Share on other sites More sharing options...
Georgie Posted September 11, 2014 Share Posted September 11, 2014 https://www.edx.org/course/utaustinx/utaustinx-ut-5-01x-linear-algebra-1162#.VBIuuvmSzfI https://www.coursera.org/course/maththink https://www.coursera.org/course/precalc https://www.coursera.org/learn/calculus1 https://www.youtube.com/user/patrickJMT https://www.khanacademy.org/ Just posting this in here in case anyone feels like they need it. I'm still fighting with the linear algebra but there's a lot of extremely useful resources out there for learning that pesky math. I only recently decided that I REALLY need that knowledge indeed so I'll be focusing on those courses heavily in the next few months. Hopefully I'll learn something =D On topic : I'm lost. I'll keep testing things out, tho. And maybe I'll come back tomorrow begging for hints =D Quote Link to comment Share on other sites More sharing options...

rodstar Posted September 16, 2014 Share Posted September 16, 2014 Nice thread I learned a lot from the last challenges. first pic is the shadow task. second pic " a new challange ?" built your own ambient occlusion in vops best regards rodstar Quote Link to comment Share on other sites More sharing options...

I'm going to attempt this in a few Quote Link to comment Share on other sites More sharing options...
Shinjipierre Posted September 18, 2014 Share Posted September 18, 2014 All right, tried the occlusion, I guess I'm not far but my result isn't great yet.Also, I did it with an attrib wrangle instead since loops are horrible to make in Vopsops. (never managed to make a for loops in vopsop) Anyway, I think that is too complicated for the beginners who wish to learn how to make vopsops.I'll try to think of another challenge that's not complicated.

Robert Posted September 18, 2014 Share Posted September 18, 2014 I'm not sure if I'm spoiling anything here but if people are still curious about the ambient occlusion despite the complexity, here is an amazing thread with a nice explanation about how it was done: http://forums.odforce.net/topic/14210-storing-light-in-points/ Quote Link to comment Share on other sites More sharing options...
Shinjipierre Posted September 18, 2014 Share Posted September 18, 2014 ah, found my problem by looking at that.Missed the fact that intersect doesn't expect a normalized vector in the direction Quote Link to comment Share on other sites More sharing options...
