Problems displayed by the cyber_visualizer tool

[lhh0916]

For the cyber_visualizer tool, I have the following three questions:

1.The cyber_visualizer tool can display point clouds normally, but the topic name can only be "/apollo/sensor/velodyne64/compensator/PointCloud2". My topic "lidar_points_2" (which has been converted to apollo.drivers.PointCloud) is not supported. Can I understand that the cyber_visualizer tool only supports specific topic names?

2.According to the results of displaying images with cyber_visualizer tool , it only supports "yuyv" format data, does not support "bgr8", but when I play "/apollo/sensor/camera/traffic/image_long" or "/apollo/sensor/camera /traffic/image_short", no error is indicated, but the image is not visible, only the black screen is displayed. Why?

3. Apollo 3.5 cyber tools should be able to add custom topic names and display them on the cyber_visualizer tool. How to do?

Thanks!

I use the apollo tag v7.0.0.0 . When I play "/apollo/sensor/camera/traffic/image_long" or "/apollo/sensor/camera /traffic/image_short" fetched by the data sensor_rgb.record , no error is indicated, but the image is not visible, only the black screen is displayed. Is this problem is solved?

[briandbl]

i use the opengl version is opengl version 4.5. the pointcloud data can show normallly. but the image data can't show. contain the first default(no_default.img) image.

[briandbl]

i use the apollo 3.5 version.

Apollo 3.5 is no longer maintained. You can migrate to a newer version, such as 9.0

do you solve the question?

[briandbl]

i found the root cause. because in the renderable_object.h virtual void Draw(void) using the GL_QUADS, in the higher opengl it is removed. so it cause the black frame. can you fix it using the gl_triangle for the compatibilty for different OPENGL VERSION? i modify it. it work for me.

[briandbl]

i mainly modify the plane.cc and plane.h.

[briandbl]

or i can push one mr to fix it.
