amin.khormaei Posted September 9, 2023 Share Posted September 9, 2023 I want to create velocity myself for points, (delta t) means (current time - previous time). I want to do that in a solver SOP with attribute wrangle, How can I get the previous frame @Time in VEX? Quote Link to comment Share on other sites More sharing options...
Atom Posted September 9, 2023 Share Posted September 9, 2023 (edited) Use a TimeShift referencing the past frame connected to input 2 of the wrangle. You can fetch any attribute from the past frame that way. vector past_v = point(1,"v",@ptnum); vector change_in_v = v@v-past_v; Edited September 9, 2023 by Atom Quote Link to comment Share on other sites More sharing options...
