Hello together,

how can i draw multiple lines and bind a texture of this. with canvas#drawLine i only can change the color of the line. or is there an alternative to draw an drawable from start position x, y to a end position x, y like a line?

it should looks like a rope, like these:


or have someone an idea, how i can draw a rope?

Since, in OpenGL, lines are not textureable, you would need to create your own API that creates a line using triangle strips, and then textures them.

Well...

Nice.. This line is texture able...

I agreed with jonbonazza ,

He have provided a good way to edit the textures..

well, maybe line is the wrong word ... i want to draw an rope . so you mean i should draw rectangles with an repeatable texture? or do you have another idea?

its quite clearly, that i cant draw a texture to an single line

Well, in OpenGL, you can only draw primitives. A rectangle is not a primitive; it is 2 triangles. What you want to do is draw a series of vertices as triangle strips, which would ultimately create a rectangular line, then map the texture to the line.

Since a rope is somewhat cylindrical you can do this...

Use GL_TRIANGLE_STRIP to create a cylinder sides. Texture accordingly for your rope.
Then you can use GL_TRIANGLE FAN for the endpoints of the rope.

If you make enough cylinders (segments) you can have the rope animate.

Is this to be 2d or 3d?

I'm currently trying to draw simple meshes using different textures (using C# and OpenTK). I read a lot about TextureUnit and bindings, and that's my current implementation (not working as expected) :
