    I How Hot Does a Human Body Burn?

    hah, yes it is/. I'm aware of the temperatures incinerators use, but those also use an external fuel, usually flammable gas of some sort. I'm interested in the temperatures reachable when the corpse is the only fuel used

    I How Hot Does a Human Body Burn?

    A curious question that's come to my mind, as I'm doing a little research for game development, aiming for realism here. Assume you have a human corpse, not doused in any special kind of fuel, but wearing cotton/polyester clothing. And you set it alight, to slowly burn over time. I've heard of...

    What's the average Body Composition by Volume?

    hi drakkith, that is pretty interesting, however it is a little TOO simple. I'm giving creatures variable anatomy (muscle.bodyfat levels) depending on factors like diet, and training. and i would really like to incorporate the difference between the density of fat and muscle in there. i'll keep...

    What's the average Body Composition by Volume?

    Hi. I'm trying to write some anatomical systems for a game I'm coding, and i need some good data to work from. Our game is about dogs, not humans, but i figure a human will be close enough What I'd really like is a case study of a specific organism, and i'd like to know the compositions, by...

    Brittleness and material behaviours

    Wow thank you arthur, I am still reading this, but i have a specific question This is a pretty nice answer, it's mostly what i suspected. However, it is missing the key detail. That is, How exactly does this "mountain" decline? Is it's slope a constant angle? Or must i define a maximum radius...

    Brittleness and material behaviours

    hi x thank you, i have been doing lots of independant research, and will continue that, but I'm also here for more of a human touch. Accurately simulating every detail of physical interactions is of course, impossible. I mostly require assistance in translating real physics into efficient...

    Brittleness and material behaviours

    hi all, I'm creating a physics based game. My design works by pre-fracturing objects into distinctive chunks at authortime, to prevent extensive processing later (some realtime fracturing will also occur, but that's unrelated). So i have lots of walls that are made up of lots of little chunks...

    Calculating the force of a collision

    a thicker wall is going to have more of each chunk's surface area connected to other chunks, and therefore will scale just fine. i don't see the issue i am also implementing compressive strength for governing the pulverising of chunks into smaller chunks, but that is actually mostly unrelated

    Calculating the force of a collision

    Help still needed. I'm making a fair bit of progress, but I'm running ionto the infinite acceleration problem. Digital objects have no "give" and are completely elastic rigidbodies, which means things just stop dead on collision. The impact happens over one frame, and is functionally either...

    How do i calculate an object's velocity along a vector?

    thank you. it turns out unity already has a native function to do this for me http://docs.unity3d.com/ScriptReference/Vector3.Project.html i'll use that, but i;m still curious about the math behind it. i shall research that a little

    How do i calculate an object's velocity along a vector?

    i'm afraid i have no idea. I'm probably wrong, but to me that sounds like a tiny modification of the same problem what exactly do you mean the angle of the velocity? as defined in radians or degrees relative to world up?

    How do i calculate an object's velocity along a vector?

    assuming 3D space. i have an object moving in a fairly arbitrary direction. Say it's being fired in an arc, and it hits a wall. What i want to find out is, how much of that object's velocity is "toward" the wall. Ie, if i define a direction from the object to the wall, how do i calculate its...

    Calculating the force of a collision

    I really don't want to do this. I originally planned to use shear, and i had to scrap that too. Apparently tensile strength is just about the only durability-related property that everyone can agree on, and for most other properties, its a crap shoot whether any particular source lists them. i...

    Calculating the force of a collision

    Hi all x I'm doing some physics related code for a game in unity engine. Unity does have a very full featured physics engine, but i can't utilise it in certain circumstances. I have a wall made up of pre-fractured little chunks, and each chunk has a connective strength which represents how...

    Calculating Moment of Inertia (2D rectangles)

    hi tim, thanks for the help! I was aware of the PA theorem, but i had already excluded it as being useful to me, I'm not fully understanding how it relates to my needs here. This theorem seems to largely depend on already knowing I through the object's centre of mass, first. it mentions 2d...
