我试图让光源在我的人物模型旋转中的OpenGL我的项目,但我试试吧,我的一切,到目前为止是我的模型旋转像疯了似的(或地板)。如何旋转固定物体(OpenGL的)围绕lightsource?
我的渲染代码如下所示:
void mainRender() {
updateState();
renderScene();
glFlush();
glutPostRedisplay();
//spin = (spin + 30) % 360;
Sleep(30);
}
void renderScene() {
glClearColor(backgrundColor[0],backgrundColor[1],backgrundColor[2],backgrundColor[3]);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // limpar o depth buffer
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
updateCam();
renderFloor();
modelAL.Translate(0.0f,1.0f,0.0f);
modelAL.Draw();
}
void renderFloor() {
// set things up to render the floor with the texture
glShadeModel(GL_SMOOTH);
glEnable(type);
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);
glPushMatrix();
glTranslatef(-(float)planeSize/2.0f, 0.0f, -(float)planeSize/2.0f);
float textureScaleX = 10.0;
float textureScaleY = 10.0;
glColor4f(1.0f,1.0f,1.0f,1.0f);
int xQuads = 40;
int zQuads = 40;
for (int i = 0; i < xQuads; i++) {
for (int j = 0; j < zQuads; j++) {
glBegin(GL_QUADS);
glTexCoord2f(1.0f, 0.0f); // coords for the texture
glNormal3f(0.0f,1.0f,0.0f);
glVertex3f(i * (float)planeSize/xQuads, 0.0f, (j+1) * (float)planeSize/zQuads);
glTexCoord2f(0.0f, 0.0f); // coords for the texture
glNormal3f(0.0f,1.0f,0.0f);
glVertex3f((i+1) * (float)planeSize/xQuads, 0.0f, (j+1) * (float)planeSize/zQuads);
glTexCoord2f(0.0f, 1.0f); // coords for the texture
glNormal3f(0.0f,1.0f,0.0f);
glVertex3f((i+1) * (float)planeSize/xQuads, 0.0f, j * (float)planeSize/zQuads);
glTexCoord2f(1.0f, 1.0f); // coords for the texture
glNormal3f(0.0f,1.0f,0.0f);
glVertex3f(i * (float)planeSize/xQuads, 0.0f, j * (float)planeSize/zQuads);
glEnd();
}
}
glDisable(type);
glPopMatrix();
}
我如何才能让这个新lightsource在我的“modelAL”对象旋转?
,我只想用球面坐标有效地做同样的事情,因为它是更清晰建议。 – imallett
