解决 Context3D not available.

本文介绍了如何在HTML-template/index.template.html中设置正确的渲染模式,包括wmode参数的使用,以及如何在AIR程序中通过修改xxx-app.xml中的配置来优化SWF在浏览器中的测试体验。重点强调了通过额外参数开启Stage3D渲染的重要性。

在html-template/index.template.html中加入:

params.wmode = "direct";  // or gpu

可选值有:auto, cpu, gpu, or direct (auto = cpu)


如果是AIR程序,则把xxx-app.xml中被注释掉的以下配置打开:

<renderMode>gpu</renderMode>

可选值同上.



使用正确的渲染模式

当您通过浏览器来测试SWF的时候,您需要确保通过额外的参数开启了Stage3D渲染。同样如果是AIR项目需要确保在配置XML中做了正确设置。

  • HTML: 在object 标签, 添加 <param value='direct' name='wmode'>
  • HTML: 在embed 标签, 添加 wmode='direct'
  • AIR: 在配置文件中改变渲染模式: <renderMode>direct</renderMode>
### Open3D Visualization Utils Python Code Examples and Documentation For working with `open3d_vis_utils.py`, this file typically contains utility functions that facilitate the visualization of point clouds or other geometric data structures within the context of Open3D. While specific details about `open3d_vis_utils.py` are not directly provided in the given references, insights into how one might approach finding relevant code examples and documentation can be derived from related information. To find useful resources regarding `open3d_vis_utils.py`, consider exploring official repositories where such scripts may reside as part of larger projects utilizing Open3D for machine learning tasks[^2]. Additionally, since similar utilities often come well-documented especially when associated with popular libraries like those mentioned, visiting the main Open3D GitHub repository could prove fruitful. The repository usually includes comprehensive guides alongside example codes demonstrating various functionalities including but not limited to visualizations[^4]. Moreover, community-driven platforms such as Stack Overflow or specialized forums dedicated to computer vision and robotics frequently host discussions around common challenges faced while implementing these tools, potentially offering practical tips on leveraging `open3d_vis_utils.py`. For direct access to usage patterns, examining contributed notebooks available through Jupyter Notebooks hosted online provides interactive demonstrations which serve both educational purposes and real-world application scenarios. ```python import open3d as o3d # Example function call assuming it exists in a hypothetical open3d_vis_utils module def visualize_point_cloud(pcd_data): pcd = o3d.geometry.PointCloud() pcd.points = o3d.utility.Vector3dVector(pcd_data) # Assuming there is an external util script providing additional features import open3d_vis_utils # Utilize custom visualization settings defined externally open3d_vis_utils.custom_visualization_settings(pcd) visualize_point_cloud([[0, 0, 0], [1, 1, 1]]) ```
