When you call glVertexAttribPointer the the array of generic vertex attribute data is defined. Draw with any geometric primitive - points, lines, and polygons - in two or three dimensions. Either by: 1) ray-casting against your scene on the [edit:] CPU, or 2) rendering all of your objects to the screen with a unique color per object, doing a glReadPixels of the resulting image, and using that for picking. opengl. Prototype public static native void glCallList(@NativeType("GLuint") int list); Source Link Document Executes a display list. What is the interest to use list (glList…glCallList). Though when we compile the same dll using GCC using wx-dev-cpp GCC appends the number of paramers the function has, so the name of the function using Dependency walker looks like. When a buffer object is bound to a. GLUT is much more easier, while many of people use SDL or SFML (they're more flexible and feature-full than GLUT). You want to apply a map of the earth to a sphere. glCallList ( list) glCallLists ( n , type , lists ) glCallLists( bytes( lists ) or lists[] ) -> None Restricted version of glCallLists, takes a string or a GLuint compatible array data-type and passes into the base function.
