Drawing coloured lines in visualizer

[ashwin.sudhir]

Functions like void engine.visualizer.renderLine3D(vec3 start, vec3 end, vec4 color)

seem to ignore the 'color' argument, I always get black lines.

 

e.g

 

vec4 vColor = vec4(1.f, 1.f, 0.f, 0.f);

 

engine.visualizer.renderLine3D( v4, v5, vColor);

 

still draws a black line.

 

Is there some other setting that needs to be changed? (nothing crosses my mind)

 

Also, renderQuad3D doesn't seem to work; I tried the same set of vertices with renderQuad and also with a set of renderLine

renderLine* worked, but not renderQuad.

I also tried the different winding orders, but to no avail.

 

 

Thanks,

Ashwin.

Try setting color alpha component to 1.0 e.g. Vec4(1,0,0,1)

[ashwin.sudhir]

Tried that already

 

vec4 vColor = vec4(1.f, 1.f, 1.f, 1.f);

still draws a black line

 

to be sure, also tried

vec4 vColor = vec4(255, 255, 255, 255);

 

but still no luck...

Just in case: do you have visualizer enabled at all?

"show_visualizer 1" console command

[ashwin.sudhir]

Yes, it is indeed enabled, just checked. I'm getting black lines, it's just the color that's a problem. Also renderQuad isn't working.

Can anyone shed light on this please, this is important for us because it'll cut down debugging time by a lot.

[ulf.schroeter]

Please provide minimal test-case showing the problem(s), so others can have a quick look on it for providing you help

Actually, the visualizer uses both renderLine3D() and renderQuad3D() to render lines and quads in green color when visualizing world sectors and navigation meshes. You can check it on samples/paths/mesh_00 sample. So I can only second the previous post: please provide your test-case.

Problem solved ?

If still not , did you try use default Unigine::Math::Vec3::BLUE as your color parameter ?
