   • Definition of math_sin function in the CPython source code?

     Top Answer

     Answered Apr 18, 2019 · 9 votes

     math_sin is defined via the FUNC1

     macro:

     FUNC1(sin, sin, 0, "sin($module, x, /)\n--\n\n" "Return the sine of x (measured in radians).")-

     where FUNC1

     is defined as:

     #define FUNC1(funcname, func, can_overflow, docstring) \ static PyObject * math_##funcname(PyObject *self, PyObject *args) { \ return math_1(args, func, can_overflow); \ }\ PyDoc_STRVAR(math_##funcname##_doc, docstring);

     so the preprocessor expands this to:

     static PyObject * math_sin(PyObject *self, PyObject *args) { return math_1(args, sin, 0); } PyDoc_STRVAR(math_sin_doc, "sin($module, x, /)\n--\n\n" "Return the sine of x (measured in radians).");

     (but then all on one line, and with the PyDoc_STRVAR macro also having been expanded)

     So math_sin(module, args) basically is a call to math_1(args, sin, 0), and math_1(args, sin, 0)

     calls math_1_to_whatever(args, sin, PyFloat_FromDouble, 0)

     which takes care of validating that a Python float was passed in, converting that to a C double, calling sin(arg_as_double), raising exceptions as needed or wrapping the double return value from sin() with the PyFloat_FromDouble function passed in by math_1() before returning that result to the caller.

     sin() here is the double sin(double x)

     function defined in POSIX math.h

     .

     You can, in principle, preprocess the whole Python source tree and dump the output into a new directory; the following does presume you successfully built the python binary already, as it is used to extract the necessary include flags for gcc:

     find . -type d -exec mkdir -p /tmp/processed/{} \;(export FLAGS=$(./python.exe -m sysconfig | grep PY_CORE_CFLAGS | cut -d\" -f2) && \ find . -type f \( -name '*.c' -o -name '*.h' \) -exec gcc -E $FLAGS {} -o /tmp/processed/{} \;)-

     and then math_sin will show up in /tmp/preprocessed/Modules/mathmodule.c.

     Or you can tell the compiler to save preprocessor output to .i files with the -save-temps flag:

     make clean && make CC="gcc -save-temps"-

     and you'll find make_sin in Modules/mathmodule.i.

   • Math pow() method in Java with Example

     The java.lang.Math.pow() is used to calculate a number raise to the power of some other number. This function accepts two parameters and returns the value of first parameter raised to the second parameter. There are some special cases as listed below:

     • If the second parameter is positive or negative zero then the result will be 1.0.
     • If the second parameter is 1.0 then the result will be same as that of the first parameter.
     • If the second parameter is NaN then the result will also be NaN.
     • The function java.lang.Math.pow() always returns a double datatype.

     Syntax:

     public static double pow(double a, double b)Parameter:a : this parameter is the baseb : this parameter is the exponent.Return :This method returns ab.

   • Vertex texture Fetch (Texture read in vertex shader)

     Top Answer

     Answered May 26, 2016 · 0 votes

     Just declare a sampler and sample it exactly as per usual. E.g.

     "#version 150\n"-in vec4 position;in vec2 texCoordinate;-uniform sampler2D texID;uniform mat4 modelViewProjection;void main(){ gl_Position = modelViewProjection * (position + texture(texID, texCoordinate));}

     That will sample a 4d vector from the texture unit texID at location texCoordinate, using that to perturb position prior to applying the model-view-projection matrix. The type of geometry you're drawing makes no difference.

   • Vertex attributes - using short instead of float for vertex positions

     Top Answer

     Answered Apr 22, 2016 · 1 votes

     I adjusted the data structure for the vertex buffer:

     struct newVertex { GLshort position[4]; // for GL_SHORT GLint normal; // for GL_INT_2_10_10_10_REV GLshort texCoord[2]; // for GL_SHORT};

     As a result I get ~20% increased performance.

   What is a vertex equidistant from a directrix?

   • The vertex A is equidistant from the focus F and from the directrix. Since C is on the directrix, the y coordinates of F and C are equal in absolute value and opposite in sign. B is the midpoint of FC. Its x coordinate is half that of D, that is, x/2. The slope of the line BE is the quotient of the lengths of ED and BD, which is x2 x /2 = 2x.

   What is the distance between a vertex and a focus?

   • The distance between the vertex and the focus, measured along the axis of symmetry, is the "focal length". The "latus rectum" is the chord of the parabola that is parallel to the directrix and passes through the focus. Parabolas can open up, down, left, right, or in some other arbitrary direction.

   What is the radius of curvature at the vertex?

   • The radius of curvature at the vertex is twice the focal length. The measurements shown on the above diagram are in units of the latus rectum, which is four times the focal length. Consider a point (x, y) on a circle of radius R and with center at the point (0, R). The circle passes through the origin.

   What are the three types of vertices in BFS?

   • We may think of three types of vertices in BFS as tree verties, those that have been taken of the data structure. fringe vertices, those adjacent to tree vertices but not yet visited, and undiscovered vertices, those that we have not encountered yet.
