Hi Manuel,
Actually I couldn't find a clean answer..
The only way I found was to set some files into ../frameworks/settings/...

Hi guys,
I am currently looking at adding some compilation option into projectdefinition.txt in macos.
When I look into https://developers.maxon.net/docs/cpp/2023_2/page_maxonapi_projecttool.html I can find the AdditionalCompileOptions which is for windows but not the equivalent for macos.
Do you know how I can pass option to xcode through the project definition ?
Thank you in advance

Thank you for your reply, I guess there is no way to observe a tag if you are not implementing it.

Hello guys,
I am trying to detect when a tag is enabled/disabled(here target camera specifically).
For that purpose I am looking at the messages coming from cinema4d.
While I can identify the messages id pattern: I receive 604, 1018484 and then 1685218156.
I cannot retrieve from which message those ID belong to.

1. How can I know when a tag has been disabled or not? If there a solution with the messages shown or a simpler one ?

I Also noticed, that I receive the same message when I click on the button located on the left of Enable (see image below).

2. What the purpose of the button located on the left of Enable?

Thank you in advance for your reply.

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

@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://developers.maxon.net/forum/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
