Graphics Rendering in Assembly

This repository contains assembly implementations for graphical rendering on two architectures:

• RISC-V: Line drawing using the Xiaolin-Wu algorithm on a .bmp file.
• x86: Rendering Mandelbrot set.

Folder Structure

RISC-V/ - Line Drawing with Xiaolin-Wu Algorithm

This folder contains an implementation of the Xiaolin-Wu antialiased line-drawing algorithm in RISC-V assembly. The program:

• Draws an anti-aliased line on a .bmp image.
• Uses floating-point calculations for smooth gradient transitions.
• Modifies pixel brightness to create a visually appealing effect.

How to Run (RISC-V)

1. Assemble the code using a RISC-V assembler (e.g., GNU riscv64-unknown-elf-as).
2. Execute the binary in a RISC-V emulator (such as QEMU).
3. Open the generated .bmp file in an image viewer to see the result.

Example:

     In             --------->        Out

                    --------->

x86/ - Mandelbrot Set Rendering

This folder contains x86 assembly implementations for generating:

• Mandelbrot set – A fractal visualization of complex numbers.

The program:

• efficiently combines x86 assembly with C programing
• Iterates over each pixel and applies fractal formulas to determine color intensity.
• Uses floating-point arithmetic (FPU/SSE).
• Outputs the result as a bitmap image.

How to Run (x86)

1. Assemble the code with nasm (Netwide Assembler):

   nasm -f elf32 mandelbrot.asm -o mandelbrot.o
