Documentation Talk:Reference Section 8.2

Poly section need updating:

• order now range from 2 to 35
• the alternative syntax with polynomial should be presented.

Hereafter a proposal (following the mesh / mesh2 approach: same object, two syntaxes)

Infinite Solid Objects

Describe a solid, possibly infinite, shape:

INFINITE_SOLID_OBJECT:

PLANE | POLY | POLYNOMIAL | CUBIC | QUARTIC | QUADRIC

---

The poly object:

POLY:

Jump to SDL

poly { ORDER, < POLY_COEFFICIENTS > [POLY_MODIFIERS] }

ORDER:

An integer value between 2 and 35 inclusive.

POLY_COEFFICIENTS:

A quantity n of FLOATs separated by commas, where n is ((ORDER+1)*(ORDER+2)*(ORDER+3))/6.

POLY_MODIFIERS:

[sturm [BOOL]] & [OBJECT_MODIFIERS]

The polynomial object:

POLYNOMIAL:

Jump to SDL

polynomial { ORDER, [POLYNOMIAL_COEFFICIENTS]... [POLY_MODIFIERS] }

ORDER:

An integer value between 2 and 35 inclusive. The sum of X_POWER, Y_POWER and Z_POWER of any xyz(): coefficient must never be greater than this integer.

POLYNOMIAL_COEFFICIENTS:

xyz( X_POWER , Y_POWER , Z_POWER):VALUE [,]

X_POWER

The power of x for that coefficient. It's a positive or null integer.

Y_POWER

The power of y for that coefficient. It's a positive or null integer.

Z_POWER

The power of z for that coefficient. It's a positive or null integer.

VALUE

The value as a FLOAT of the coefficient of the polynomial equation for that powers of x,y and z. If a coefficient is not specified, its value defaults to 0.

POLY_MODIFIERS:

[sturm [BOOL]] & [OBJECT_MODIFIERS]
