I have webgl 3D scene with background image and few shapes with textures.
I want to add some lines and other shapes and apply on them default color which not affect the shapes with textures.
How can I do this?
this is what I have now:

gl.clearColor(0.0, 0.0, 0.0, 0.0); //alpha=0 for background img
  • \$\begingroup\$ Question is ambiguous. Do you want to color the shapes? Or change the depth buffer color? \$\endgroup\$ – Krythic Oct 21 '16 at 13:13
  • \$\begingroup\$ @Krythic, color the shapes that not have textures \$\endgroup\$ – arii Oct 21 '16 at 13:38
  • \$\begingroup\$ It depends on what framework you're using. For OpenTK, GL.Color3(Color.Red); \$\endgroup\$ – Krythic Oct 21 '16 at 13:44

  • \$\begingroup\$ Most frameworks of OpenGL are 1:1 in terms of the api. Your case should be gl.color3f(1.0f,0.0f,0.0f); \$\endgroup\$ – Krythic Oct 21 '16 at 13:59

You have to use shaders to apply color to objects..

In fragment shader you can specify it with gl_color = vec3(r,g,b,a);

Glcolor3f it's deprecated..
