The smaller the number, the slower the object is. Rtri + = 0.2f; // increase the rotation variable of the triangle (new)Rquad-= 0.15f; // reduce the rotation variable of the Quadrilateral (new)Return true; // continue running} Finally, change the title content in window mode.

Change the error code after qt4 In the QT OpenGL Chinese tutorial (1)

The code is not analyzed here because it is enough in the tutorial. If you are interested, you can check the code yourself. This tutorial comes from the original neheopengl Chinese tutorial (http://www.yakergong.net/nehe/), but it has a bad place, that is, when I go to see, it can not download the code ~~~~ Maybe my character is poor. It can be used as a referenc

Lesson 1Fog: This course is based on the Code of Lesson 7th. You will learn three different calculation methods for fog and how to set the fog color and scope.This tutorial is written by Chris aliotta.Do you want to add fog effects to your OpenGL program? I will teach you how to do this in this tutorial. This is my first tuto

OpenGL-GLUT tutorial (iii) glut window settings

GLUTTutorial Prepare for transformation window Download the following vcpus and run the program (glu0.zip) (this is the project in the previous section ). You will see two windows: a console window and an OpenGL window. Change the window size so that the height and width are no longer equal, and the triangle is deformed. This occurs because you have not correctly set the projection matrix. The default value is the Perspective Projection Matrix and t

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

; // increase the rotation variable of the triangle (new)Rquad-= 0.15f; // reduce the rotation variable of the Quadrilateral (new)Return true; // continue running} This lesson is over again. 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

Lesson 1Texture ing of graphic fonts: In this lesson, we will create a font with a texture based on the previous lesson, which is really simple.After publishing the first two tutorials on Bitmap fonts and contour fonts, I have received many emails. Many readers want to know how to assign texture maps to fonts. You can use the automatic texture coordinate generator. It generates texture coordinates for each polygon in the font.A small comment. This code is specially written for windows. It uses t

OpenGL-GLUT tutorial (4) glut Animation

GLUTTutorial Animation So far, we have an OpenGL window with a white triangle, but it is not exciting at all. Now let's go to this tutorial to rotate the triangle. Let's go back to the main () function and add some additional settings. First, tell glut that we want a dual-buffer. The dual buffer creates a smooth animation by painting in the latter buffer and constantly switching the front and back buf

OpenGL Getting Started Tutorial 3

The size of the point defaults to 1 pixels, but it can also be changed. The changed command is glpointsize, and its function prototype is as follows:void Glpointsize (glfloat size);Size must be greater than 0.0f and the default value is 1.0f, in pixels.Note: For specific OpenGL implementations, there is a limit to the size of the point, and if you set a size that exceeds the maximum value, the setting may haveProblem.Examplevoid Mydisplay (void){Glcle

OpenGL tutorial (5) shader (2) uniform variable

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

Android OpenGL ES development tutorial (16): viewing and modeling (modelview) Transformation

The transformation between viewing and modeling is closely related to the camera to place the tripod and adjust the position and angle of the object to be photographed. Usually, these two transformations are defined using a modelview transformation matrix. For the same coordinate transformation, you can use different methods to imagine this transformation. For example, if you want to translate a distance from the

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
