Hi Ferdinand, thank you for your detailed reply.
I am looking for hit point. Then if I understand well, my only way would be to use GeRayCollider on all objects ?

Best,

Hi guys,
I would like to compute the distance from a point to a mesh while editing a document.

• Requested method:
  - [IN] start point
  - [IN] direction vector
  - [IN] radius (area to look)
  - [OUT] position of a hit if it exist (or a distance to the starting point).

• Current plugin structure implementation:

  MessagePlugin objects' scene coordinates.

• Example:
  

Here I would like to know the first element which is hit by the blue line from the camera.
I took here the camera to have a visualization, however it can be a random start point.

I considered few options:

1. Geraycollider: gives the distance if you know the target object, however I don't know it.
2. VideoPostData plugin to get VolumeData and then use TraceGeometry method. However, it seems that it is not called and the time but only when a rendering is done.

Do you have any hint or recommended method to do that?

Thank you in advance
Best

@cairyn Thank you!

Hello guys,
I am working with cameras to do some computation I need to retrieve its current view volume. I call view volume, the visible scene's "cone" from the camera pov.
See picture below (this cone is visible when the option "Show Cone" in camera object is switched on):

1. Does it exist a function returning this volume no matter what kind of camera is used?

2. While I can compute it for perspective camera, I couldn't guess the right parameters to compute it for parallel camera.

struct frustum{
 Float farVal, nearVal, right, left, top, bottom;
}f;

cam = GetCamera()) {
Float near = 0;
Float far = 1000;
Float focusLength= getParam(CAMERAOBJECT_TARGETDISTANCE, DA_REAL, cam).DReal;
		if (getParam(CAMERAOBJECT_NEAR_CLIPPING_ENABLE, DA_LLONG, cam).DLLong != 0) {
			near = getParam(CAMERAOBJECT_NEAR_CLIPPING, DA_REAL, cam).DReal;
		}
		if (getParam(CAMERAOBJECT_FAR_CLIPPING_ENABLE, DA_LLONG, cam).DLLong != 0) {
			far = getParam(CAMERAOBJECT_FAR_CLIPPING, DA_REAL, cam).DReal;
		}
		auto fov_vertical = getParam(CAMERAOBJECT_FOV_VERTICAL, DA_REAL, cam).DReal;

		
		auto widthHalf = focusLength * maxon::Tan(fov / 2.0)/100.0;
		auto heightHalf = focusLength * maxon::Tan(fov_vertical / 2.0) / 100.0;
		
		f.farVal = far;
		f.nearVal = near;
		f.right = widthHalf;
		f.left = -f.right;
		f.top = heightHalf;
		f.bottom = -f.top;
		return 0;
	}

Any help is welcome.
Thank you in advance

Thank you m_adam it works perfectly !
Here is the code if it helps someone

	AutoAlloc<AtomArray> pList;
	FilterPluginList(pList, PLUGINTYPE::COMMAND, true);
	for (size_t i = 0; i < pList->GetCount(); i++)
	{
		auto elem = static_cast<BasePlugin*> (pList->GetIndex(i));
		DiagnosticOutput(elem->GetName()+ ", "+ String::IntToString(elem->GetID())+ ", " + GetCommandHelp(elem->GetID()));
	}

I have also another question, before I was trying to discover commands thought the menu then I could categorize it.
Do you think there is a way to collect such information (for instance know that "New project" command is located into file submenu.

Thanks

Hello Guys,

1. Is it possible to get a full list of command ID ?

For now I understand from different forum posts that the only way is to get it from the command palette (for instance in https://plugincafe.maxon.net/topic/3168/2548_command-id/2)
For now I am doing this kind of recursion to get a list of command from the ui.
The code below shows me two kind of results:

  1. IDM_XXX
  2. PLUGIN_CMD_${ID}

The first one is a string while the second contains an id but does not corresponds to the targeted command id.

void EnumerateCmds(BaseContainer* item) {
	BrowseContainer bc(item);
	Int32 id = 0;
	GeData* dat = nullptr;
	while (bc.GetNext(&id, &dat))
	{
		switch (id) {
			case MENURESOURCE_SUBMENU:
				DiagnosticOutput("SUBMENU [");
				EnumerateCmds(dat->GetContainer());
				DiagnosticOutput("]");
				break;
			case MENURESOURCE_STRING:
				DiagnosticOutput("MENURESOURCE_STRING " + dat->GetString() + "[");
				EnumerateCmds(dat->GetContainer());
				DiagnosticOutput("]");
				break;
			case MENURESOURCE_COMMAND:
				DiagnosticOutput("MENURESOURCE_COMMAND=" + dat->GetString())
				break;
			case MENURESOURCE_SEPERATOR:
				break;
			case MENURESOURCE_SUBTITLE:
				DiagnosticOutput("subtitle="+ dat->GetString());
				break;
			case MENURESOURCE_MENURESOURCE:
				DiagnosticOutput("MENURESOURCE_MENURESOURCE=" + dat->GetString() + "[");
				EnumerateCmds(dat->GetContainer());
				DiagnosticOutput("]");
				break;
			case MENURESOURCE_SUBTITLE_ICONID:
				DiagnosticOutput("MENURESOURCE_SUBTITLE_ICONID id value: " + dat->GetInt32());
				break;
			case MENURESOURCE_ASSET:
				DiagnosticOutput("MENURESOURCE_ASSET" + dat->GetString() + "[");
				break;
			default:
				DiagnosticOutput("error");
				break;
		}

2. Are command's id same for their icon ? Otherwise how could we fetch it?

Thank you in advance for any help
