Why does OpenGL use degrees instead of radians?
The OpenGL designers were never afraid of mathematics, and knowledge of linear algebra is essential for all but the simplest OpenGL applications. I think it can safely be assumed that OpenGL programmers are familiar with angles in…

Rotate point about another point in degrees python
If you had a point (in 2d), how could you rotate that point by degrees around the other point (the origin) in python?
You might, for example, tilt the first point around the origin by 10 degrees.
Basically you have one point PointA and origin that…

Convert radians to degree / degree to radians
Are there build-in functions in R for the conversion of radians to degree and degree to radians?
So far I wrote my one own functions:
rad2deg <- function(rad) {(rad * 180) / (pi)}
deg2rad <- function(deg) {(deg * pi) / (180)}
#test:
rad2deg(pi)…

Calculating degrees between 2 points with inverse Y axis
I'm creating a simple 2D game in javascript/canvas.
I need to figure out the angle of a certain object relative to my position.
So: say I'm at (10,10) and the object is at (10,5) - that would result in 90 degrees (as positive Y is down, negative Y…

map degrees to 0 - 360 in python
is it possible to map a value of rotation to be inside the range of 0-360 degrees?
For example:
a angle of -10° should be 350°
a angle of 760° should be 40° degrees?
Is there an easy solution? Maybe in mathutils?
best,
chris

Convert an angle in degrees, to a vector
I'm doing some game programming. FWIW I'm using XNA, but I'm doubtful that this is relevant.
I'd like to convert degrees to a directional vector (ie X and Y) with magnitude 1.
My origin (0,0) is in the upper left.
So I'd like 0 degrees to convert…

Converting Degree, Minutes, Seconds (DMS) to decimal in PHP
Currently, I'm learning to use Google Maps API. From what I read, the API require the latitude and longitude in Decimal Degree (DD).
In my database, the data is stored as DMS.
Example, 110° 29' 01.1"
I would to ask if you have any DMS to DD in PHP.…

How to compute correctly rounded trigonometric functions in degrees?
How could I define trigonometric functions that take arguments in degrees instead of the usual radians, and compute correctly rounded results for these arguments?
Multiplying the argument by M_PI/180.0 before passing it to the corresponding function…
