second green vertex. The lower left vertex of the triangle is set to green.Glcolor3f (0.0f, 1.0f, 0.0f); // set the current color to green.Glvertex3f (-1.0f,-1.0f, 0.0f); // bottom left Set the third vertex, that is, the last vertex. Set the color to blue before you start painting. This will be the right bottom vertex of the triangle. When glend () appears, the triangle is filled. However, because each vertex has a different color, it seems that the color is sprayed out of each corner, and it i

For convenience, the vector is usually set to (0, 1, 0) or the Y axis in the coordinate system.

Learning OpenGL (3) drawing spiral graphics [Email protected] Http://blog.csdn.net/kezunhai In OpenGL, graphics are composed of some basic elements, which interpret a set of fixed points or vertex lists as some images drawn on the screen. The smallest element in OpenGL is a vertex. There are 10 elements in

Nested display list To support more complex plotting, the display list also supports nesting. That is, when creating a display list using glnewlist () or glcalllists () call the defined display list. Theoretically, the number of nested layers in the generated list can be 2 ^ 31-2, but in fact there are two reasons why this is not supported. First, when the number of nested layers increases, it takes a lot of resources and time to create a display list

Migration policyThere is a high risk of making a backward incompatible version of the software. When people need to rewrite their software or maintain a fragmented version in order to support versions of two languages or frameworks, the risk is that they never make the transition and stay on the old version forever, Or worse, that they the switch to another framework.For the reason Python versions 2.6 and 2.7 include both several forward compatibility

That must not be, maybe he happened to do one of the 19 questions, but the actual level is not so high, the other physics problems will not do, if this is the case, we say that the generalization error is relatively large. If this assessment really chooses the highest level of students, then we say that the generalization error is relatively small. The generalization error is
