Aryesia :
I am doing a project on OpenGL 3D. I have several figures, and when I rotate the camera (scene), the figures seem to go beyond it (or beyond Viewport)
Normal condition:
Cropped figure:
How can I increase the viewing area? Or what can be done in this situation?
Now I am trying:
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glDepthFunc(GL_LEQUAL);
glfwPollEvents();
glPushMatrix();
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
GL11.glViewport(0, 0, width, height);
GL11.glMatrixMode(GL11.GL_PROJECTION);
glLoadIdentity();
But it does not bring results.
Rabbid76 :
It seems that the object is clipped by the near plane of then orthographic projection. Change the near plane to solve the issue.
The orthographic projection matrix is set by glOrtho
.
By default the projection matrix is the Identity matrix. That is the same as you would do
GL11.glOrtho(-1, 1, -1, 1, 1, -1);
Increase the distance to the near and far plane to solve the issue. e.g:
GL11.glMatrixMode(GL11.GL_PROJECTION);
glLoadIdentity();
GL11.glOrtho(-1, 1, -1, 1, 10, -10);
