[clutter] x,y,z coords
Hello, I've noticed that the clutter api provides placement for actors, but only oddly in the sense that the actors exists in a 3d space, but the set_position calls only take shorthanded 2d coordinates. I find it weird that if I want an actor like a rectangle or text actor rotated around the y axis I have to rotate it with the rotation api. Why can't one specify the 3d coords for three of the points of the actors if I happen to know what they are? In reading and trying out the API, I get the sense that the API was a 2d layout system that later got applied to 3d objects. Basically, if I were to design a 3d box with text actors on each face, it would be needlessly complicated to initialize it. Also, if I weren't to use the timeline to animate stuff and instead I animated it myself, there doesn't seem to be a good way to do that either because there doesn't seem to be a good way to get at the mesh points of any particular actor. The reference manual hints at the possibility, but doesn't explore it at all. Am I missing some large part of the API or something? I see clutter_vertex_* but no real way to create an actor and set the 3D verticies manually. Thank you. -pete -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com

I'd be happy with 2D elements--for example a text entry area which can only be a rectangle, but there is no good API to place them or manipulate them 3D. I'm looking for the ability to mix opengl and GUI elements together. For example, rendering an editable text area on the side of a box, then doing opengl markup graphics on the text itself, overlayed onto the text which is context sensitive to the text layout. Of course, the box is a real object, so it can move around in an environment modeled by (as an example) the open dynamics engine. That sort of thing.

[clutter] rectangles and text
Hello, My name is Peter Keller and I'm very new to clutter and have a question about how to implement something. (I've started initially learning clutter 1.0). I would like to have a rectangle, possibly with a texture on it and subject to lighting effects, that I could scale, rotate, translate in 3D, but also has a text editor overlayed onto the rectangle and over the texture. I've written some example programs that use rectangles and text views, but it seems I don't know how to put the text into the rectangle. Ultimately, I'd like to write a text editor that can exist on arbitrary 2d surfaces arbitrarily oriented in space, and be able to click on them to move the cursor position and select text with the mouse. Is such a thing doable in clutter? I've written plenty of opengl code and enough gtk+ to get my way around in it, so I just need some small examples and I should be on my way. Thank you. -pete -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com
