WebNov 17, 2012 · To improve it: 1) Add an image of your stick being rendered, 2) add more useful "information": is the stick being held by a character, do you want a physics simulation, or just run the stick through an animation loop, 3) try to explain more carefully what mouse clicks and moves should do to the stick (preferably with a drawing), and 4) explain … WebIf you want to use the point size you manually set at a distance of, say, 150 units from the eye, just use 1/(150^2) as the quadratic factor (and zero for the constant and linear factors -- if anything, you may want to use some small number like 0.01 for the constant factor just to avoid potential divisions by zero).
WebA point light is a light source with a given position somewhere in a world that illuminates in all directions, where the light rays fade out over distance. Think of light bulbs and torches as light casters that act as a point light. In the earlier chapters we've been working with a simplistic point light. WebGet the 2D picking point in OpenGL coordinates Note that OpenGL coordinates are counted from the bottom left corner of the window, in contrast to most windowing libraries which use the upper left corner as the origin. project(self, worldCoordinate=None) Get the screen coordinates for the event w/out the pick-point requires that worldCoordinate and
WebJul 3, 2024 · OpenGL supports several basic primitive types, including points, lines, quadrilaterals, and geneneral polygons. All of these primitives are specified using a sequence of vertices. How does the OpenGL library break polygons into triangles? OpenGL has many geometric primitives, but the fundamental drawing primitive is the triangle.
WebOpenGL (Open Graphics Library) is a cross-platform, hardware-accelerated, language-independent, industrial standard API for producing 3D (including 2D) graphics.
