mapping:cawe:editingtools:editfaceprops [2010-09-24 17:01] Carsten Removed description of limitation "Apply Projective" tool mode: This corner case is rarely encountered, and if so, CaWE itself explains the problem (with solutions) clearly. |

| * **Apply View Aligned**: This mode works like a slide-projector: The material is projected onto the clicked surface, where the base of the cameras view pyramid defines the plane of projection. (Contrary to a real slide-projector though, parallel rather than perspective projection is employed. Variants of parallel projection are also employed by the other apply modes and are more appropriate for the task at hand.) The orientation attributes are also taken into account. This is a great mode for texturing a rocky wall or any other irregular shape (that consists of multiple adjacent surfaces) seamlessly. | * **Apply View Aligned**: This mode works like a slide-projector: The material is projected onto the clicked surface, where the base of the cameras view pyramid defines the plane of projection.

| * **Apply Edge Aligned**: This mode makes sure that when you click on a surface //next// to the previously picked one (i.e. left-clicked, possibly with ''ALT''), the material is seamlessly aligned across the common edge. This is a worthwhile feature especially when the two surfaces are not coplanar. (It even works when the clicked surface is not immediately adjacent to the other.) \\ FIXME What exactly are the restrictions when Bezier patches are used? | * **Apply Edge Aligned**: This mode makes sure that when you click on a surface //next// to the previously picked one (i.e. left-clicked, possibly with ''ALT''), the material is seamlessly aligned across the common edge.

| - | * **Apply Projective**: Like Apply Normal, but this mode also applies the //texture planes U- and V-vectors// of the picked surface to the clicked surface. This mode is the generalization of both the Apply Normal as well as the Apply View Aligned modes, and as the underlying technique is a mathematical projection, it is called Apply Projective. Refer to the advanced section below for more technical information. \\ This is the mode of choice whenever you want to texture a Bezier patch exactly like an adjacent brush face. For example, if you have a wall or a floor that is made of both brush faces and Bezier patches, and you want to apply the material on the brush faces seamlessly to the Bezier patches, just pick up the surface attributes from a brush face, and Apply Projective to the Bezier patches. \\ Mode limitations: Picking up the attributes from Bezier patch surfaces may not provide sufficient attribute information for this mode to work in some cases. This is true whenever the Bezier patches surface was defined by non-projective means. This situation is pointed out by the colored backgrounds of the Orientation fields in the dialog. | + | * **Apply Projective**: Like Apply Normal, but this mode also applies the //texture planes U- and V-vectors// of the picked surface to the clicked surface.
