About
================================================================================
GameDev Calc is a calculator for game and graphics developers. It's different
from standard Windows calculator, but I believe it's quite intuitive and useful.
The calculator is SIMD. It's just like manually executing shaders. Basic data
type is not a single number, but a vector of up to four floating point numbers
which you can treat as vector (x,y,z,w) or color (r,g,b,a).
Next to standard operations like addition, multiplication or sine, there are
many special operations available, like calculating length of a vector.
Available operations include:
- Finding minimum, maximum, clamping to 0..1 or to given range, linear
interpolation.
- Normalizing vectors, calculating vector length, distance between points,
dot product, cross product, vector projection, vector reflection.
- Converting angles between degrees and radians.
- Converting colors between RGB and HSB, calculating color brightness.
- Finding coefficients of linear and quadratic equation passing through given
points.
The way GameDev Calc works is much different than traditional calculator, where
you can see only the last number entered. Here you can see all the history of
your computations in form of a stack and you perform all operations on this
stack. For example, to calculate 2 * 3 + 4, you must:
- Add 2. Stack contains: 2.
- Add 3. Stack contains: 2 3.
- Perform multiplication. Stack contains: 2 3 6.
- Add 4. Stack contains: 2 3 6 4.
- Perform addition. Stack contains: 2 3 6 4 9. Result is at the end.
You can freely move vectors around the stack, delete them, duplicate them,
insert separators and store vectors in additional memory, so you are not limited
to operating only at the end of the stack.
GameDev Calc gives you possibility to read and enter vectors as strings in one
of the standard formats or your custom formats that suit your needs. For
example, you can write and read vector (0, 0.5, 0.752, 1.0) as:
- D3DXVECTOR4(0.0f, 0.5f, 0.752f, 1.0f)
- 0, 128, 192, 255
- 0xFF0080C0
