WebJust like a graph, the center has coordinates (0,0) and the y axis is positive above the center. This seems unnatural because graphics applications usually have (0,0) in the top-left corner and (width,height) in the bottom-right corner, but it's an excellent way to simplify 3D calculations and to stay resolution independent..

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 … Web31 de jan. de 2024 · This is not technically an answer to your question, but is a better work around in my opinion. You can pass the dimensions of the boxes and the radius of the corners to the fragment shaders and round the corners that way. Basically, you take the current texture coordinates, multiply each coordinate of it by the dimensions of the … diary of my father
OpenGL 101: Drawing primitives - points, lines and triangles
A work around is to draw the triangles with GL_FILL first in background color (in my case, white), and then draw the edges separately. But doing so results in artifacts similar to the z-fighting phenomenon, i.e., some edges seem thinner than others or even vanish, as shown below.

Depending on your skill level, solid wireframes may be an option. NVIDIA's example images show highlighting edges of triangles, but that's something you can work around. You can use a geometry shader to generate barycentric coordinates, and then check them in your fragment shader to determine distance of a … diary of my emtions
