In Topic: How to shade hair (line segments) in OpenGL

OK, I'll try that and see how it works.

The thing is I am not sure how to pass that additional vertex. How can the shader know when its time to use it ?

If I just add a vertex to my buffer, the result will be the same I think?

 

EDIT: I managed to get better results with precalculating the segment directions, fill them in an array and pass them to opengl. But the shading is not smooth and you can see the different line segments, not sure how to interpolate it.

I use the same vertex buffer for "vert" and "vertNext", just with different offsets. I guess that when "vert" points to the last element of the buffer, "vertNext" is some undefined garbage and weird things happen.

 

Any suggestion how can I get the line segment direction ? Do I need to calculate it outside of the shader and later pass it ?


In Topic: AI is harder than I thought

If you want you can have a look at this code: click

Specifically line 146 - computerMove() function.

I have written this version in my early years when I was learning C++ and some parts of the code look horrible :D

but the algorithm for the AI should work just fine.

I've started watching the linear algebra videos some time ago and they are really nice. But it seems short on exercises (or not deep enough)
