 create texture and paint vertex with color for make morph

 

 

 

benefits : 

 

all process in GPU

size is very low 

fast reaction 

 

disadvantages :

 

collision is not work

always have problem with compute normal(for smooth normal)

build a good morph is take a time

really nice

How does this work? I understand that the painted areas are the parts that are moving, but how are they moving?

hi ozRocker

 

after painting you can get this color in the vertex shader and you can define function for move that

 

like this : 

 

vec3 color = texture2D(ref,uv).rgb;

 

// rotate_x function for rotate in shader  new pos = rotate_x(old pos , deg , center );

position = rotate_x( position , 30.  * color.g, vec3(0.,3.,0.));

i try work to   scan  points ( test ) and generated paint function  

 

that like rig but in the rig you paint vertex in maya or max in 3d area

 

but here you paint in texture ( thats good easy change and we can make multi rig with multi texture and you can use the z brush )

and in this way we have restriction like only 8 color you have to manage

Huge!

deltakosh i started eash.js (easy shader )you can add this after babylonjs and you can use all tools 

 

i think this way is good and independed way for shader

 

sample :

 

1: mesh.material = eash.Shader( eash.solid(0xff0000)+eash.fresnel() , scene);

 

2: mesh.material = eash.Shader( eash.outline() , scene);

 

3: mesh.material = eash.Shader( eash.walk('texture.jpg') , scene);

 

 

and work for tools for generated and preview   and add in the github

Hey this is really awesome because in theory, it should be possible to make a single mesh that is sent to the GPU, and then change the clothing textures and do all the animations on the GPU to create different characters in different animation states without using too much time in JS, which is usually the bottleneck  in WebGL due to the single thread

 

The tricky bit though is, how do you convert animations from a tool like Blender into shader instructions? I guess you'd need to write a script for that. Coding every animation step by hand will never produce nice looking results unless you are willing to spend weeks tweaking a single walk cycle

 

p.s. I don't think collisions will be a problem... in most games a bounding box is used for collisions anyway for performance. Just make sure the box is big enough to cover the maximum dimensions and it should be reasonable. It's only going to be an issue for something like a FPS where you need very accurate collision shapes.

it is not theory . in real you can do it .

Well, I don't mean it's theory that you can do it. I mean it's theory that it's awesome.

There might be some reason we didn't think of yet that makes it turn out to be not so awesome when you take it to the next steps
