复纹理图。最后,用宽度和高度创建一个 2 维图。数组中的数据类型由 GL.GL_UNSIGNED_BYTE 定义。下面,将看到如何给枪的每个顶点加上纹理图。

在枪上使用纹理图

定义了纹理图之后,需要指定对枪的哪个顶点进行贴图。请修改 Gun 类的构造函数,如清单 16 所示。

清单 16. 修改 Gun 类的构造函数

public Gun() {        texture();        GL.glNewList(this.getListIndex(), GL.GL_COMPILE);          GL.glColor4fv(RED);          GL.glBegin(GL.GL_QUADS);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v1);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v3);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v4);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v9);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v3);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v4);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v5);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v6);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v10);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v6);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v5);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v7);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v4);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v5);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v7);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v8);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v2);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v10);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v6);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v3);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v10);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v7);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v13);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v14);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v8);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v9);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v12);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v13);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v1);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v9);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v12);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v11);            GL.glTexCoord2d(0.0f,0.0f); GL.glVertex3fv(v1);            GL.glTexCoord2d(1.0f,0.0f); GL.glVertex3fv(v2);            GL.glTexCoord2d(1.0f,1.0f); GL.glVertex3fv(v14);            GL.glTexCoord2d(0.0f,1.0f); GL.glVertex3fv(v11);
