kGridPoints, RGBuniforms, PointCloudUniforms etc NOT FOUND in Renderer.swift #2

Open shaheer34mts opened 3 months ago

shaheer34mts commented 3 months ago

Hi @christophebedard I have imported all the files in the xcode project, but when I build it gives multiple errors in Renderer.swift file that it cannot find certain variables (kGridPoints, RGBuniforms, PointCloudUniforms ) and many more. Apparantly (I might be wrong) they have been defined in the shadertypes.h file. But it cannot find it.

I have properly linked the bridging-header file in the build configuration as well. but still, it is unable to find those variables. What am I missing/slash doing wrong? I have attached a picture of errors as well 447560115_1541854390010715_8548498549981039894_n

They are here: https://github.com/christophebedard/ipad-lidar2ros/blob/master/src/ShaderTypes.h. Your project configuration might be wrong.

@christophebedard Thanks for the reply. Indeed the issue was with the configuration. I managed to solve it and run the app on my iPhone 13 Pro Max. However, I can't publish the data over ROS. As you can see in the image below, the "switch" for the remote bridge turns on irrespective of the IP address I put in it. However, the switch still turns on even if I don't launch the ros2 web bridge. But, no data is published. Do you know what the problem can be? Thanks for the help again. Image

Unfortunately, I never tested it on an iPhone, and I do not have a Mac anymore.

I haven't looked at the code in a long time, but I believe it's the masterSwitch in https://github.com/christophebedard/ipad-lidar2ros/blob/master/src/RosControllerViewProvider.swift.

@christophebedard Finally I managed to publish the cloud from iPhone 13pro Max over ROS 2. Apparantly the code works when you press the "build" button from x-code, and then put the IP address. But when you just launch the application from mobile by disconnecting it from the Macbook, it stops connecting. Have you encountered this behavior?

I don't remember much, but I don't believe so. I'm pretty sure it worked fine for me when not connected to my Mac using a cable. I could deploy the newly-built app to my iPad and launch it without a cable.

Maybe it's related to your network.
