上诉工程向量的代码实现

以下是一些可能用于实现GPU的图像渲染测试的代码实现：

1. 图像分辨率：

import cv2

image = cv2.imread("test_image.jpg")
height, width, channels = image.shape

2. 图像格式：

import cv2

image = cv2.imread("test_image.jpg")
image_gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

3. 渲染模式：

import pyrender

scene = pyrender.Scene()
mesh = pyrender.Mesh.from_trimesh(trimesh)
material = pyrender.MetallicRoughnessMaterial(baseColorFactor=[1.0, 0.0, 0.0, 1.0])
node = pyrender.Node(mesh=mesh, matrix=np.eye(4))
scene.add_node(node)
light_node = pyrender.Node(light=pyrender.SpotLight(color=np.ones(3), intensity=3.0, innerConeAngle=np.pi/16.0))
scene.add_node(light_node)
camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0, aspectRatio=1.0)
scene.add(camera, pose=np.eye(4))
renderer = pyrender.OffscreenRenderer(512, 512)
color, depth = renderer.render(scene)

4. 光源：

import pyrender

scene = pyrender.Scene()
mesh = pyrender.Mesh.from_trimesh(trimesh)
material = pyrender.MetallicRoughnessMaterial(baseColorFactor=[1.0, 0.0, 0.0, 1.0])
node = pyrender.Node(mesh=mesh, matrix=np.eye(4))
scene.add_node(node)
light_node = pyrender.Node(light=pyrender.SpotLight(color=np.ones(3), intensity=3.0, innerConeAngle=np.pi/16.0))
scene.add_node(light_node)
camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0, aspectRatio=1.0)
scene.add(camera, pose=np.eye(4))
renderer = pyrender.OffscreenRenderer(512, 512)
color, depth = renderer.render(scene)

5. 材质：

import pyrender

scene = pyrender.Scene()
mesh = pyrender.Mesh.from_trimesh(trimesh)
material = pyrender.MetallicRoughnessMaterial(baseColorFactor=[1.0, 0.0, 0.0, 1.0])
node = pyrender.Node(mesh=mesh, matrix=np.eye(4))
scene.add_node(node)
light_node = pyrender.Node(light=pyrender.SpotLight(color=np.ones(3), intensity=3.0, innerConeAngle=np.pi/16.0))
scene.add_node(light_node)
camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0, aspectRatio=1.0)
scene.add(camera, pose=np.eye(4))
renderer = pyrender.OffscreenRenderer(512, 512)
color, depth = renderer.render(scene)

6. 场景复杂度：

import pyrender

scene = pyrender.Scene()
for i in range(10):
    mesh = pyrender.Mesh.from_trimesh(trimesh)
    material = pyrender.MetallicRoughnessMaterial(baseColorFactor=[1.0, 0.0, 0.0, 1.0])
    node = pyrender.Node(mesh=mesh, matrix=np.eye(4))
    scene.add_node(node)
light_node = pyrender.Node(light=pyrender.SpotLight(color=np.ones(3), intensity=3.0, innerConeAngle=np.pi/16.0))
scene.add_node(light_node)
camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0, aspectRatio=1.0)
scene.add(camera, pose=np.eye(4))
renderer = pyrender.OffscreenRenderer(512, 512)
color, depth = renderer.render(scene)

7. 渲染速度：

import pyrender
import time

scene = pyrender.Scene()
mesh = pyrender.Mesh.from_trimesh(trimesh)
material = pyrender.MetallicRoughnessMaterial(baseColorFactor=[1.0, 0.0, 0.0, 1.0])
node = pyrender.Node(mesh=mesh, matrix=np.eye(4))
scene.add_node(node)
light_node = pyrender.Node(light=pyrender.SpotLight(color=np.ones(3), intensity=3.0, innerConeAngle=np.pi/16.0))
scene.add_node(light_node)
camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0, aspectRatio=1.0)
scene.add(camera, pose=np.eye(4))
renderer = pyrender.OffscreenRenderer(512, 512)
start_time = time.time()
for i in range(100):
    color, depth = renderer.render(scene)
end_time = time.time()
render_time = (end_time - start_time) / 100.0
