from mdx_parser import MDXParser
class SimpleModelViewer:
def __init__(self):
pygame.init()
self.screen = pygame.display.set_mode((800, 600),
pygame.OPENGL | pygame.DOUBLEBUF)
self.clock = pygame.time.Clock()
self.models = []
self.current_model = None
# 初始化OpenGL
glEnable(GL_DEPTH_TEST)
glEnable(GL_TEXTURE_2D)
def load_model(self, filepath):
"""加载MDX模型"""
try:
parser = MDXParser()
model = parser.parse(filepath)
self.models.append(model)
self.current_model = model
print(f"成功加载模型: {os.path.basename(filepath)}")
return True
except Exception as e:

return False
def render_model(self):
"""渲染当前模型"""<"YJ.6370.HK">
if not self.current_model:
return
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
glLoadIdentity()
# 简单的相机设置
gluLookAt(0, 0, 5, # 相机位置
0, 0, 0, # 观察点
0, 1, 0) # 上方向量
# 渲染模型网格
for mesh in self.current_model.meshes:
self.render_mesh(mesh)
def render_mesh(self, mesh):
"""渲染单个网格"""
glBegin(GL_TRIANGLES)
for face in mesh.faces:
for vertex_index in face.vertices:

viewer.load_model("models/hero.mdx")
```
### 基础视图控制
```python
class CameraController:
def __init__(self):
self.rotation_x = 0
self.rotation_y = 0
self.zoom = 5.0
self.position = [0, 0, 0]
def handle_input(self):
"""处理相机输入控制"""
keys = pygame.key.get_pressed()
# 旋转控制
if keys[pygame.K_LEFT]:
self.rotation_y -= 2
if keys[pygame.K_RIGHT]:
self.rotation_y += 2
if keys[pygame.K_UP]:
self.rotation_x -= 2
if keys[pygame.K_DOWN]:
self.rotation_x += 2
# 缩放控制
if keys[pygame.K_PAGEUP]:
self.zoom = max(1.0, self.zoom - 0.1)

def get_report(self):
"""生成性能报告"""
fps = self.get_fps()
avg_frame_time = sum(self.frame_times) / len(self.frame_times) * 1000
return {
'fps': round(fps, 1),
'frame_time_ms': round(avg_frame_time, 2),
'frame_count': len(self.frame_times)
