Form Intersection Please help me level up - darktiste - 11-17-2017 Hi i would like to clear some confusion if i made some error will doing Form intersection thank you Here 2 version the second one is suppose to be the correction Please feel free to explain and correct my misunderstanding of some of the concept RE: Form Intersection Please help me level up - neopatogen - 11-18-2017 (11-17-2017, 03:46 AM)darktiste Wrote: Hi i would like to clear some confusion if i made some error will doing Form intersection thank youThe corrected version looks good! A good way to check the intersections that you doubt about is to recteate your simple forms in Sketchup. Free version is enough for that purpose.There's an option there to show hidden lines (like if you were "drawing through"). Check it out if you haven't already, it's quite intuitive for beginners in 3d. I used this method to check my Drawabox intersection excercise. Btw where is your excercise from? Some art course?

I am really still a newbie not played with many 3d software so far so for the moment it not a viable way to correct my error rapidly.I am currently mixing study with dynamic sketching and drawbox i found that drawing on pinterest and i figure i could use it to understand a bit more about intersection on paper and i applied correction because i personnaly i think it good to take other people work and look at what you can learn from them.Being able to self correct is sometime i want to be able to do.(11-18-2017, 02:44 AM)neopatogen Wrote:(11-17-2017, 03:46 AM)darktiste Wrote: Hi i would like to clear some confusion if i made some error will doing Form intersection thank youThe corrected version looks good! RE: Form Intersection Please help me level up - Amit Dutta - 11-24-2017 These things look off to me A: Basically the depth of that intersection area, when compared to the other things going on in the scene doesn't match up. The intersection might be right assuming those two boxes were interacting on their own only, but the position in space of the those two boxes in relation to the rest of the scene then makes the intersection one that wouldn't happen given the entire 3d space. The box that is tilted upwards should be in front of and overlapping the lower one so there would be no interaction at all. B: This intersection is wrong. Your first try was better though not right. The vertical line of the intersection of the box tilted down would not go all the way to the edge of the other box. Revisit it C: The ellipse angles are incorrect for the angle of the box surfaces D: I don't think that intersection looks right, especially the lower one.

RE: Form Intersection Please help me level up - neopatogen - 11-25-2017 I mistook the 1st attempt for a corrected one sorry :) Obviously yes it was better. Now thatI have a bit more time to look closely, here's what I could spot. If I'm wrong somewhere hopefully smb corrects me as well. But seriously, if nobody does draw-over and you don't like 3d, cut a sausage with a knife under an angle for a cylinder.. And.. maybe try cutting apple for a sphere? :) Real life objects are always great to observe and experiment with. RE: Form Intersection Please help me level up - darktiste - 11-25-2017 I will close this post for now on i learn a great deal so thank you both |
