Web13 de dez. de 2024 · Hi everyone, currently, I’m solving the problem of drawing the non-occluded triangle edges of a mesh by drawing all the triangles with polygon offset enabled (both factor and units >0) and then drawing all the triangle’s edges as lines with depth testing enabled.. This method conflicts with some post-processing that uses depth values … WebFor instance, to draw our triangle A we execute all the above calls. Then, to draw other shape B we also have to run these steps for the specific case of B. And if we want to draw A again we have to re-run all these steps again. And so on. The process is cumbersome. OpenGL provides another concept for simplifying this: the Vertex Array Object (VAO

Web31 de dez. de 2024 · In this case I am comparing each pair of triangles that are adjacent and comparing its normals. If the normals are not the same then it's an edge, so I draw a line. However, when combining primitive shapes to form a more complex shape ( current rendering ), I don't know how to remove the edges of the faces that are coplanar with the …
WebIn the linked question, the OP was looking for an algorithm which could generate a plane with only one OpenGL triangle strip. He came up with a solution that works almost perfectly: The order of the vertices for the strip is indicated by the arrows: 1-5-2-6-3-etc. The only drawback is that it also generates one unnecessary triangle on every ... paper comedyWeb5 de nov. de 2024 · Modified 5 years, 5 months ago.
