Fill the color of the triangle:The Fill color function for Glcolor (3/4) * (R,G,B) 3 or 4 means that the numeric type rgb/rgba;* represents Rgba (B,i.) will eventually be mapped to [0-1].How to map is to take the value of the Write/current type maximum value such as Byte is -128~127 glcolor3b (1,0,0) equivalent to glcolor3f (1/127f,0,0) less than 0 whe

Original post address: http://ogldev.atspace.co.uk/www/tutorial05/tutorial05.html In this tutorial, we will be exposed to a new shader variable uniform variables. The difference between this variable and the attribute variable is that when each vertex shader is called, the corresponding attribute values of the vertex are loaded from the vertex buffer according to the position of the attribute, while the uniform variable remains unchanged for each dra

Lesson 1Spherical ing: This will teach you how to wrap the environment texture on your 3D model and make it look like it reflects the surrounding scenes.Sphere environment ing is a method for creating fast metal reflection effects, but it is not as accurate as in the real world! We will create this tutorial from the code of Lesson 18 and teach you how to create this effect.At the beginning, let's take a look at the introduction in hongbao. It defines

Now you have mastered how to create objects in 3D space. The OpenGL screen must be imagined as a large drawing paper with many transparent layers. It is almost a cube composed of a large number of points. These points are filled with cubes from left to ri

tutorial code, we wrapped these common functions and created the technique class, its Inheritance class will focus mainly on shader special effects. Each technique must first call the init function for instantiation. The derived class of techniqu must first call the init function of the base class (this function creates an OpenGL program object ), you can also add your own private functions. After a techni

The first type of transformation is to change the position of the object (pan), rotate, dimension (indent). These transformations allow us to place an object anywhere in the 3D world

Original post address: http://ogldev.atspace.co.uk/www/tutorial06/tutorial06.html In this tutorial, we start to change the position of a 3D object, such as translation, rotation, scaling, and so on. The operations of object location changes are usually implemented through matrices. Each change is represented by a matrix. If an object performs multiple location operations, the corresponding matrices can be multiplied, multiply the coordinates of the v

GLUT Tutorial Keyboard example ------ Scenario roaming II In this section, let's take a look at the previous example. This time we will use advanced keyboard control. In the initialization section, we have two variables: deltaangle and deltamode. These variables control rotation and movement of cameras. When the value is not 0, the camera performs some operations. When the value is 0, the camera does not move. The initial values of these two variable

GLUT Tutorial Sub-menuIn the previous chapter, we learned how to create a simple menu. Now let's take a look at how to add a cascading submenu. The creation of sub-menus is the same as the function used to create menus. After creating a menu, we add the Sub-menu as an entry. Use the function maid to do this: void maid (char * entryname, int menuindex); parameter: entryname: Sub menu name. Menuindex: Sub-menu index. This is the value returned by the s

Lesson 1Besell surface: This is a course about mathematical operations, and there is nothing else. Come on, look at it with confidence.Besell Surface By David nikdel (ogapo@ithink.net) This tutorial is intended to introduce the surface of besell. I hope someone who knows more about art can use her to make some cool stuff and show it to everyone. In this tutorial, you cannot create a complete shell database.

GLUT Tutorial MouseIn the previous sections, we saw how to use the keyboard function of GLUT to increase the interaction of an OpenGL program. Now it's time to study the mouse. The glut mouse interface provides some column options to increase the interaction of the mouse. That is, to detect mouse clicks and move the mouse. Detect mouse ClicksLike keyboard processing, Glut provides a method for registering

Brief Introduction The Nehe tutorial introduces the extended (Arb_multisample) Multiple sampling techniques for OpenGL in this lesson. With this technique, full-screen anti-aliasing can be achieved. This will make the graphic look more beautiful. In OSG, multiple sampling is opened and closed as stateset of nodes, and the implementation process is very simple.
