[SOLVED] engine.visualizer.getMessageExtent()

[ulf.schroeter]

Problem

 

We are using engine.visualizer.renderMessage2D/3D() for rendering interactive object multi-line text annotations while the user moves the mouse cusor over objects. At the moment text output is always centered on the specified anchor point. This is too restrictive.

 

 

Unfortunately there is no engine.visualizer method for calculation the screen size/extent of the output text message which could be used to calculate an appropriate text offset in screen coordinates so the text can be positioned left/right/top/bottom aligned (or whatever) in relation to the mouse screen position.

 

Proposal

 

Addition of a simple function engine.visualizer.getMessageExtent() so users can calculate text offsets.

[frustum]

engine.visualizer.renderMessage() functions will receive an additional argument for text alignment:

 

vec3(0,0,0) - center

vec3(1,0,0) - right

vec3(-1,0,0) - left

vec3(0,1,0) - bottom

vec3(0,-1,0) - top

Yep, good solution. In the meantime I discovered WidgetCanvas text functionality with even more capabilities for text formating, background polygons etc..
