176 | * This has to handle both when a user draws on the terrain *and* when a user selects | ||
177 | * a selection of AABB on terrain and applies whatever routine the client requests | ||
178 | * There's something currently wrong with the brushsize --> size conversion.. however | ||
179 | * it's workable.. just unpredictable. | ||
180 | * | ||
181 | * North is always higher and East is always higher | ||
182 | * in the AABB representation | ||
183 | * | ||
184 | * Therefore what we're doing is looping from south to north and west to east | ||
185 | * and applying the associated algorithm with the brush. | ||
186 | * | ||
187 | * This works good on the fast ones, but things like smooth take 12 seconds a single click.. | ||
188 | * for now, smooth won't be 'selectionated' | ||
189 | * | ||
190 | * If the user draws instead of selects, north will = south, and east will = west. | ||
191 | * if the user selects, then the selection is inclusive | ||
192 | * it'll always affect at least one point on the heightmap. | ||
193 | * | ||
194 | * that means we use the <= operator | ||
195 | * | ||
196 | * Again, libTerrain is yx instead of xy.. so, it's reflected in the function calls | ||
