I develop a fps game.I attached gun to camera.But i can't put gun to front of objects.In first picture everything is normal.But in the second picture gun is rendering at back.I can scale objects.If i scale objects , i need to raise zfar value.Will the game use more memory if i do that?What can i do otherwise?
A simple solution for this problem is to render the weapon first with a stencil value. Afterwards render the rest with stencil test on to avoid rendering over the weapon model.
Thanks Ashaman73. I read wiki and morrowland.com tutorials.But I couldn't.Can you post some code or tutorial link?
I think the simplest solution is to render the scene, then clear the z buffer, then render the FPS hands/weapons. I suspect Ashaman73's solution is more efficient because it saves some fill rate, but you might not have a handy stencil bit spare
Thanks C0lumbo.It worked :) .I post codes.Maybe, it can help someone.
void RenderFrame()
{
glViewport(0, 0, g_windowWidth, g_windowHeight);
//glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
glClearColor(112.0f/255.0f,162.0f/255.0f,1,1);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glMatrixMode(GL_PROJECTION);
glLoadMatrixf(&g_camera.getProjectionMatrix()[0][0]);
glMatrixMode(GL_MODELVIEW);
glLoadMatrixf(&g_camera.getViewMatrix()[0][0]);
glEnable(GL_TEXTURE_2D);
Draw_Skybox(0,0,0,500,500,500); // Draw the Skybox
glScalef(0.05f,0.05f,0.05f);
heli->draw();
glClear(GL_DEPTH_BUFFER_BIT );
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glRotatef(180,0.0f,1.0f,0.0f);
glTranslatef(0,0,25);
weapon->draw();
glDisable(GL_TEXTURE_2D);
RenderText();
}
