Factory method is creational design pattern, this method provides one of the best ways to create an object. Abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme.

Builder Design pattern designed to provide a flexible solution to creating complex in oops programming. Adapter pattern makes two incompatible interfaces compatible without changing their existing code. Decorator pattern is a design pattern that allows behavior to be added to an individual object,dynamically. Strategy design pattern helps to choose a specific implementation of algorithm or task in run time.

Observer design pattern has a one-to-many relationship so that when one object changes state, the others are notified and updated automatically.

Multiple Threads access the critical section in race condition, So protect that we used Synchronization instance or block to protect it. Most of the projects used multithreading system, Multiple ways are there to create and instantiate threads along with that maintain the lifecycle of threads. Also, Create deadlock and then Remove it.

The purpose of this question to test your problem solving skills. Also it checks that you stand with the team during any difficult technical issues. We explain it with sample answer of how to answer this question. Mostly entry level candidates face this questions in behavior rounds. CGPA reflects how serious you are in your curriculum and takes initiative means you are innovative. Even if your don't have these you can present very decent answer so interviews wont consider you as a bad hire.

This is mostly happens in real project that you missed deadlines. But through this question interviewer want to judge your technical skills. Take time explain properly. We provide sample answer for experienced as well as freshers level candidates, how to answer this question. You need explain most impressive accomplishment in your tech carrier or college curricula.

You should answer this question based on your resume. But, we provide sample answer for this question for experienced as well as entry level candidates, they can refer it and frame there answer before interview. This shows that you can work and perform in pressure situation also. Explain with sample answer how you use this question to showcase your technical competency.

As a leader of any project, many times we take wrong decisions which can make our customers unhappy. This is quite common in tech jobs. This questions required you to elaborate and think outside the box. Instructor Profile:. Just finish this course and you will receive multiple offer letters.

Hal ini membuat gerakan halus hampir tanpa biaya coding. Untuk menambahkan inersia, kita hanya perlu mengingat beberapa persamaan fisika, seperti yang satu ini:.

Pertimbangkan bagaimana mobil bekerja: Anda tidak benar-benar mengatur kecepatan kendaraan namun menggunakan pedal untuk menambahkan percepatan atau pengereman untuk itu. Jadi kita benar-benar perlu untuk mengimplementasikan kontroler kami dalam hal percepatan, tidak kecepatan secara langsung. Kontroler yaw kami dengan demikian akan. Baris pertama adalah hanya versi percepatan kontroler awal kami.

Kemudian, kami menggunakan dua baris untuk membatasi kecepatan, jadi kami tidak bisa berputar lebih cepat dari awal ketetapan kami. Baris keempat mungkin yang paling tidak jelas dari keseluruhannya. Untuk memahaminya, perhatikan bahwa kondisi jika diaktifkan jika tidak kiri maupun kanan yang ditekan. Dalam hal ini, kami perlu memperlambat rotasi secara progresif. Kami mencapai hasil ini dengan mengalikan kecepatan saat ini dengan faktor pengereman misalnya, 0, Baris terakhir hanya update yaw sesuai dengan kecepatan rotasi yang dihitung.

Sekarang kita telah melihat bagaimana menerapkan kamera untuk FPSS, sekarang saatnya untuk membuatnya. Kami akan menggunakan primitif karena mereka seperti OpenGL dan DirectX menyediakan cara mudah untuk menentukan jenis kamera. Menentukan lokasi kamera adalah sepele.

Sekarang, untuk menentukan tampilan-pada titik, kita akan menggunakan beberapa trigonometri lagi. Jika Anda memahami sin dan cos digunakan untuk memajukan sesuai dengan sudut yaw, berikut ini harus menjadi jelas:. Secara intuitif, tampilan-pada titik ditempatkan dalam arah yang sama kami tuju, dengan demikian, menggunakan tahap yang sama untuk menghitung itu sangat mudah.

Baris yang benar-benar menempatkan kamera adalah dua baris terakhir, tapi saya memberikan kode kamera setup penuh untuk kelengkapan. Ingat bahwa panggilan gluPerspective set parameter optik seperti bidang pandang, rasio aspek, dan sebagainya, sedangkan gluLookAt menempatkan kamera melalui sembilan parameter dikelompokkan dalam triplet. Triplet pertama adalah posisi kamera, yang kedua adalah tampilan-pada titik, dan yang ketiga adalah vektor mengarah ke atas, yang kita perlu untuk model kamera yang lebih canggih.
