Android3d game development series (2) color rendering and Rotation Next we will perform a simple operation for the triangles and squares we draw, such as color rendering and rotation. First, let's look at the running effect: 1. color rendering of the image There are two main ways to color a graphic: Smooth coloring and plane coloring. As shown in, the triangle uses smooth coloring to combine different colors of the three vertices of the triangle to create a beautiful color mix. The quadrilatera

Local coordinates and world coordinates The local coordinate is a relative coordinate, which is relative to the parent node or the relative position of a node you specify. The origin of the local coordinate is in the lower left corner of the reference node. The world coordinate is an absolute coordinate. It is based on the coordinate origin in

matrix creates a transformation of the object to be presented from a special perspective. Projection and photography views in OpenGL ES 1.0 In es 1.0 API, you need to create projection and photo views respectively and add them to the OpenGL environment. 1. Projection Matrix ---To recalculate the coordinates of graphic objects so that they can be drawn at the correct ratio, you need to create a projection matrix using the geometric shape of the device screen. The following sample code demonstrat

I installed the software in the Linux system:/lib/ld-linux.so.2:bad ELF interpreter How to solve, here I analyze there are two, one is commonly used installation because of the system software bit problems, such as: 64-bit system installed 32-bit programs, The other is that cross-compiling does not have that file or directory, so let's look at how to solve the problem.Problem one, 32-bit program resolution is installed on 64-bit systemsis because a 32-bit program is installed in a 64-bit systemW

Problem one, 32-bit program solutions installed in 64-bit systems is because 32-bit programs are installed in a 64-bit system Workaround: The code is as follows Copy Code Yum Install glibc.i686 Problem two, resolving the cross compilation environment error # ARM-LINUX-GCC Hello.c-o TT/HOME/GL/USR/LOCAL/ARM/4.3.2/BIN/ARM-LINUX-GCC:/HOME/GL/USR/LOCAL/ARM/4.3.2/BIN/ARM

states. The Int type state variable is also provided here, which indicates the current state. Like other screens, gamescreen first executes the present () method to draw the game interface, and then listens for touch screen events in the update () method. The difference is that different States must be processed in these two methods. Let's take a look at the present () method. The Code is as follows: @Override public void present (float deltaTime) { GLCommon

The confirmation method is as follows: Search for the following two files in the system directory (c: \ windows \ system32 by default for WINXP: Opengl32.dll and glu32.dll, if any, indicate that your video card has implemented the OpenGL interface. 2.

The following is the code for the fragment shader.Code for the > Fragment shadervoid Main (void) { Gl_fragcolor = VEC4 (1.0, 1.0, 1.0, 1.0);}With regard to color, basically use VEC3 or VEC4 case is more. Because it is usually using RGB or RGBA, you need four or three elements. This time using the VEC4 is all the parameters are 1.0 of the vector, the color is white [red, green, blue, opacity of the elements are the largest = white].compiling code, generating shadersNext, we look
